Ever walk into a kitchen where sits a cake that has 1 slice left, yet someone ate all but the small remaining outer crust? That bugs that crap out of me. If you're gonna snack on a piece of cake (or cookie or whatever) then eat the entire piece, don't eat part of it where the rest is rendered useless for anyone else.

I don't know who it was that left the small piece with a bite taken out of it, but that person is my "A-Hole of the Day"
