Cashiers of Reddit, what customer(s) have you had that have either left a good impression or a terrible one?

Once upon a time I worked a cash register and this older middle ageish black guy tried to pay for his food with change. He may have had health issues or just been on something because he dropped his change on the floor, then fell down as he tried to pick it up. So he’s on his hands and knees failing to pick up all the change so we tell him “you can just take the food we’ll pick up the money later”.

He got a pretty decent discount and we got to get the checkout line moving again.
