When you go to a gas station and try to use a $20 bill to make a purchase and are told they don't have the change for it. This is a gas station/convenience store. Being denied for my purchase and treated extremely rudely because you are trying to buy something is ridiculous. It's 11:30 on a Saturday night. I do not recommend this gas station go to the one next door if you want to be treated to properly and be allowed to make your purchase without being told you have to buy more items because they can't break a $20!
