<p>When I want to pick up a check, I excuse myself near the end of the meal, go find the waiter and take care of the whole business out of sight. When everyone is finished and someone wonders about the check, I just say “this time it’s my treat” or whatever is appropriate.</p>
<p>If they ask you for a recommendation of restaurant, since you are local, I think it is really easy to pick a casual place you eat regularly, where they know you, and it doesn’t seem odd then you take care of the bill.</p>
<p>My concern is that since they invited you, they may feel they should pay! If I found myself in this situation, I would avoid the whole scenario by inviting them to my home for dinner. But I may be more comfortable than most entertaining strangers. I have had lots of practice. If you know other local students and parents, I’d make a little party. But again, this isn’t everyone’s comfort level. But just another suggestion :)</p>
