Not in a good mood one day to begin with, I pull up to a drive through burger place, and order a burger and fries. I'm told it's cheaper to order the "meal", which of course includes the drink. So I order a meal. Girl asks me what I want to drink...I tell her nothing. She says she can't give me a meal unless she gives me a drink. I tell her to give me just the burger and fries, she says she can't...so, I tell her give me a cola. She hands me the glass, I remove the lid, pour the drink out the window and hand her back the glass. Wasteful, yes...did I feel better afterwords, YES! Silly restaurants.
