What is the big deal with dreadlocks?
I design for a number of military programs and defense contractors. Anything seen as overtly counterculture is out of place in an engineering office like ours and would probably disqualify you from an engineering job here. We rely on people being confident enough to speak freely in our design discussions. Days were that wearing a suit with stripes to an interview would get you disqualified from some places - too stylish.
I have no issue with dreadlocks on the produce guy at the organic market. Only two types of people show up to engineering work dressed like a bum: geniuses and idiots. Don't make me guess which one you are.
And to add another thing to the list - a student came in, took up my time asking for free design advice and free sample parts. He kept his iphone below the table and texted while we were talking, as if I wouldn't notice. I complained to the instructor who had recommended he come to me.
