I have one, sort of? Well, I'm not sure, but I'll let eHell judge.
We went to McDonalds the other night. That'd be my sister, my BF, and I. We have one of two usual tables we like sitting at, that would be two round ones with high chairs in the center of the restaurant. We'll sit elsewhere, just, you know, our favorites.
So of course, that's where we go to first. We then saw them, and one was covered in trash and the other one had just started, by a family of 10 or so who managed to squeeze themselves into a four person booth. Instead of throwing their trash out, they let it accumulate on two tables so they could all sit at the booth. One of the things was a half-eaten burger.
I'm not so sure if its flaky or not. I mean, they did keep three tables all to themselves, plus some of the loose chairs. On the other hand, it wasn't that busy and we did sit elsewhere.
Maybe it's just more What The Fineish than anything else.
