Larger bathrooms on planes means smaller seats for the other 200 people.
I have not found interstate rest stops to be dirty. Not like some restaurants, which have caused me to refuse to eat there.
When walking in a city and nature calls, I go into a fancy hotel lobby and find the ladies room.
The problem with unisex single user restrooms is that men who have no aim, the dribblers, those of the wandering stream, may have used it just before you.
I think single use bathrooms should be unisex, most of the restaurants I work on require two bathrooms because I am required one for each sex, but they are so tiny that if we could just have unisex bathroom they would only need one. When you are talking about a place with a dozen or so tables requiring two handicap accessible restrooms makes a real impact on the space. I worked on a yoga studio and the building department told me I had to put men’s and women’s signs on the restrooms for the inspection, but they would turn a blind eye if they turned into unisex rooms after that. When you start talking about larger bathrooms, I’m still old fashioned enough not to be comfortable seeing a bunch of guys at urinals, but I also went to college with unisex rooms and do not care what’s going on in a stall behind a door. There’s ways to design a unisex bathroom that I think everyone can be reasonably comfortable with. For example, I see a lot of restrooms in NYC restaurants where all the sinks are shared by both sexes and are open to the public (i.e. not behind a door) and the stalls are in enclosed rooms.
I always dress a little nicer than usual in cities for just this reason. I want to look as though I belong in that hotel, preferably for a business meeting.
I have even stopped at a non fancy hotel- think Holiday inn or Hampton inn and walked in like I belonged there. There is usually a bathroom on the ground floor for guests.
One of the many repulsive things about public restrooms is entering after somebody who has, ahem…spent some time…in the stall!
I’m not usually grossed out by public bathrooms. Cleaning the public pool boys/men’s locker room and toilets Saturday mornings as part of a summer job during college was gross.
More bothersome was our London trip when there were few available and some cost money for not so great facilities (but needed them). I can handle outhouse type park facilities and porta potties. A medical school classmate accused me of having “TB”- tiny bladder- as I needed those rest stops on a trip. Now my need for fluids plus meds mean fluids in/out. I will avoid the unflushed toilet but also will go ahead and flush it if the previous occupant didn’t (or the automatic mechanism failed in its job). Not always pleasant but being pragmatic goes a lot further than allowing oneself to think about it.
As long as we’re complaining, I find it rather foolish that people wipe off the grocery cart handle before shopping. Then they proceed to pick up merchandise that others have touched. Handwashing before touching food/eating is a must.
We’re all parents here and a long time ago needed to deal with diapers and the like. You get used to bodily functions. And you do not regret when that need is past!
I guess I’ve seen a lot worse in the OR. Some personalities do not get as grossed out by things as others.

I read this article years ago and found it informative and amusing. To @VeryHappy Point, we shouldn’t be touching the handles.
I thought that they wiped it because little kids sit in those carts, and little kids are horrible germbags.
I work in the OR and do fine, but disgusting bathrooms still gross me out.
In the region I’m currently visiting most bathrooms don’t provide toilet paper. Instead, adjacent to every toilet there is flexible hose with a spray nozzle on the end, similar to the hoses that many kitchen sinks had a couple decades ago. Once one has done their duty, they position the nozzle underneath and hose everything off. It sounds strange, but it works pretty well, except that there’s no way to dry yourself off.
It’s kind of like using a bidet toilet seat, but more awkward. Another drawback is that sometimes water sprays upward and out the gap between the rim and the seat, and ends up on the floor. Fortunately, all bathroom floors here are sloped and have floor drains.
I’m guessing my indifference to most bathroom issues folks here have is part of what’s given me my pretty darn good immunity. 
After having traveled in various places abroad, there really isn’t a “bad” bathroom in the US. I’m perfectly fine pretty much everywhere. It’s a place to do a job, not somewhere I’m moving into.
Personally, I wish all bathrooms were unisex. Having to wait is worse than anything else and the men’s bathrooms I’ve been in (when I don’t care to wait and have someone to watch the door) are no different than women’s bathrooms - for each it mainly depends on who has been there before you and how good the cleaning staff is.
I loved the bathroom setup at my youngest son’s college (Eckerd in FL). They had groups of 4 unisex bathrooms - each private with a full length lockable door and additional open center sinks between them for those just wanting a sink or mirror (with private sinks in the individual bathrooms too). Can’t get more ideal than that. They were far cleaner than the bathrooms at each of my other lad’s schools - single gender traditional types.
@sherpa, I just had a client whose bathroom I am remodelling request one of these bidet hoses. We tried to sell her on the Washlet, but she was adamant about the hose. My kid had a similar arrangement in Jordan in his apartment. After washing themselves off they were expected to put toilet paper in the trash because the sewer system was not up to large quantities of toilet paper. After he got used to it, he thought it was far more hygienic.
I didn’t think I’d be able to find this 13 year old thread about bidets - but here it is: http://talk.collegeconfidential.com/parent-cafe/235233-bidets-p1.html
@mathmom - “bidet hoses”. That’s the perfect term for them. Right now I’m in the waiting room in a very modern hospital and the toilet setup here is just as in America, but with the added bidet hose. If we were in Japan or South Korea there would be bidet toilet seats, but here is sort of in between those countries and the U.S.
We’ve installed bidet toilet seats in all of our bathrooms at home and, personally, I don’t understand why modern western toilets don’t provide a water cleansing method.
