I love this because of how down to earth it is. I find myself in situations like this all the time. Well, it's more like my brother. There are places that will get rid of the bun. You just have to tell them you're allergic to gluten. Just say "no bread" and they'll put it in a container.
Granted, I don't know if that would work at the restaurant shown here. Rewards card? Yeah, that shows up all the time in my life. I'm really trying to save as much money as possible. This is like something that would appear in brewstew.
