"Oh wait, I think I hit the wrong button." She mashed the stylus against the card reader touch-pad. "There...wait that ain't right. Let me just clear it out." Immediately, she hammered an imaginary nail through the screen with her jabs. Forceful lady.
"Wait, why is this screen here? I don't want to sign for this, I want to run it as a debit."
"I'm sorry Ma'am, you have opted to run it as a credit card, I can't change it at this point." My coworker told her.
"Yes you can, you can change it. I know, I work in retail too." She pointed to her polo shirt with a major grocery logo on it. "You can change it."
"I'm sorry Ma'am I can't. The transaction has already been run as a credit in our system. If you want, we can do a return and then you can repurchase as a debit..."
"No! That will take up to ten days for me to get my money back! You don't know what you are doing, I want to speak to a manager!"
The assistant manager listened to the complaint, looked at the screen showing a credit transaction for $10, and informed the lady the credit had already been processed. Would she like to do a return?
"Your machine is broken! I should be able to cancel this!"
"No Ma'am, it isn't broken, it's just that in our system—"
"This is unbelievable. There are some dumb-@$$'s working in this state!"
In my mind, a British voice suddenly spoke from the card reader announcing "You ARE the weakest link! Goodbye." Then it spontaneously combusted in front of the indignant woman. My day was suddenly better.
