When you are rude to your barista they simply get you back by giving you decaf instead of full test in your latte. Your favorite dry cleaner also has a trick when you bring in a bag of laundry that you've just informed them your dog has pissed on. Theyre happy to take that dripping, wet bag from you, but when you get it back and you put those clothes on, you'll realize the dry cleaner pissed on your clothes before they gave them back.
