I got a haircut, paid with $100 bill. Barber says I need to get change next door at the convenience store, comes back with a clearly fake $100 bill (not the one I handed him which I got from the bank) and says it's fake. So unethical. They robbed me of $100. Lessons learned: never let a $100 bill leave your sight when paying for something, and never return to Moreno.
