I work graveyard in a grocery store, and see incredible stuff almost every night. I used to wrk late night in a convenience store and was constantly amazed by people, including the 450+ lb. woman who came in evry night and bought three boxes of Twinkies and a 600ml diet Coke. It was the absurdity of the diet Coke... like, I was thinking 'hun, that ain't gonna make a difference after you snarf down those Twinkies.'
