There's a great Tyler Durden quote in Fight Club about this.
Narrator : Tyler, you are by far the most interesting single-serving friend I've ever met... see I have this thing: everything on a plane is single-serving...
Tyler Durden : Oh I get it, it's very clever.
Narrator : Thank you.
Tyler Durden : How's that working out for you?
Narrator : What?
Tyler Durden : Being clever.
Narrator : Great.
Tyler Durden : Keep it up then... Right up.
