(I am working my first job as a cashier in a large and popular retail store. I have only been there a couple of weeks. Note that while we may have coupons out on the registers, we are not allowed to offer them up. If a customer sees it in time, they may use it. If not, they can take one for another time, or just move on.)
Me: *completing the transaction* “And if you could just sign this for me?”
(Once we reach the point of a signature, there’s no going back. If something is wrong by then, a manager must do a post-sale void or adjustment.)
Customer: *sees a coupon specifically for the only thing she’s buying* “Wait. Can I use this?”
Me: “I’m sorry, but I can’t apply anything else at this point. I can’t go back from here.”
Customer: “Well, can’t you just put it in?”
Me: “I don’t even have the option to go back at this point. We can only complete the transaction; maybe customer service can help you.”
(This goes on for a moment, before she finally completes it, takes her receipt, and goes to customer service. A little while later, a coworker of mine from customer service comes up to me at my register.)
Coworker: “Did you have a lady over here, complaining about—” *picks up coupon* “—one of these?”
Me: *laughing* “Yes.”
Coworker: “I just wanted to apologize for her. She was rude to me, too.”
(I told him not to worry about apologizing for her, because some people are just like that. According to him, she complained about our training. Sorry we can’t apply coupons AFTER a transaction!)
