Actual conversation.  *place 20 ounce drink on 7-11 counter. "You know the 44 ounce is 25 cents cheaper." "It's already poured, this is all I want." "But you could get more soda and save a quarter." "There are people waiting." "I'm just saying it's a better deal.  Don't you want more soda?" *slap the drink across the counter and walk out.
