Poor Money Management

People who can't pay for a $100 purchase with one type of payment probably shouldn't be buying the items. A customer paid $20 in cash, $20 in check, $20 on one credit card, and $40 on another card. I got called up because the cashier wasn't sure if we could do that. Yes, but we prefer not to. Especially since the computers sometimes freeze when too many types of tenders are entered (and the credit card companies charge per swipe of the card).

Then there are the customers whose cards are declined. Some of them are shocked, even angry, and blame the cashier. "My card is good!" they insist as they make the cashier run it again. Nope, it's not. It's declined. Again. Other people shrug as they hand another card, "Try this one." It's declined too. "How 'bout this one?" When every card they have is declined, they write a check. It's declined because they have a history of writing bad checks. Then (after 10 minutes) they pull out cash to pay for the stuff. Why didn't they do that to start with?!
