Yeah I was thinking along the lines of Seinfeld, but obviously it doesn't have to be that cheesy. That show just generally has a really good grasp of everyday idle chatter, and maybe even defined it culturally to some extent.

e.g.

Oh you got the big salad? I had a friend once who asked for a big salad. I paid for it, but my girlfriend took credit when she handed her the bag! The audacity!
