Seriously Needs Some Change

(A group of five friends come up to the stand to buy pretzels. We have a deal going on: buy three pretzels get the fourth for free.)

Customer #1: “We need FIVE pretzels.”

Me: “All right. You’re going to be getting one of those for free today, so your total is going to be $12.36!”

Customer #1: *hands me their card, gets declined*

Me: “Oh! Your card was declined.” *inspects card a bit more to find that it’s a gift card that says $24 on it written in sharpie*

Customer #1: “Well, I just used it in a store five minutes ago, so it should be working. Scan it again!”

Me: “How much did you spend at the store?”

Customer #1: “Uhm. Like $14.”

Me: “The card has $24 , so since you spent $14, you only have $10 and the order is $12.36.”

Customer #1: “Um, okay.” *to Customer #2* “Gimme $2!”

Customer #2: *slowly digs through purse to find a wad of singles; [Customer #1] snatches $2*

Customer #1: *to Customer #3* “Gimme $0.36!”

Customer #3: *dumps out change purse on counter and counts out $0.36 in pennies*

Me: “Thank you… Now I just need to rescan your card to get the $10 since it declined it the first time!”

Customer #1: *hands me a $20*

(I and all the other customers just stared at her in disbelief.)
