I work fast food. It’s fast paced. There are thousands of cards with thousands of designs. We don’t accept American Express but if it’s accidentally run it goes thru and the employee must foot the entire bill whether it’s 2 or 80 dollars. We have to take the customers card and run it ourself. Once in a while one slips thru. It’s so dumb. Especially new people who aren’t familiar with the cards or which is which.
