This happens to me a lot. I just can't seem to grasp that people eat breakfast as McDonald's. I mean...I don't. So on those rare occasions I'm there before 10:00 AM, I seem to forget and automatically order what I usually get.
I enjoy how Jan looks in panel 2. I think that's one of the more accurate representations of him.
And here's the first faceless background people. If they're not going to be too close to the area your supposed to be paying attention to, then I try to keep them simple. I had a design for them in my head, but then I thought why waste them on background characters. I think I made the McDonald's employee a pig and the guy eating some sort of cat.
