Does anyone pay you extra just because you did it?
When you buy groceries, do you pay your, say $100, then give a few more bucks to the cashier who took your money and bagged your groceries?
Do you tip a server for good service? Do you also tip a server for poor service? Well, 98 per cent per cent of you do.
Throwing money in the garbage isnât illegal, but perhaps if it were, people would stop tipping, because it has indeed become just as counterintuitive.
