So here’s the thing: When you purchase a two dollar and fifty cent beer on happy hour and give me three one dollar bills and tell me to “keep the change”, I hate you. I can live with you tipping me fifty cents, but don’t insult me by saying “keep the change”, that’s an expression to be used when there might be a chance that you would be expecting change and you’re letting me know you don’t. On the same topic, when you purchase a two dollar and fifty cent beer on happy hour and give me three one dollar bills and you take the fifty cents I only put on the bar so other people can see you’re not tipping, I hate you too.
