Don’t Discount The Customer’s Ability To Discount, Part 3

(I work for a popular pharmacy/retail chain. We have a rewards card that can be linked to a customer’s online account or their mobile app that gives them the ability to send coupons directly to their card electronically, eliminating the need for paper coupons. The customer simply scans their card at check out and their coupons will appear to me, the cashier, and I can put them in right from there.)

Customer: “I was supposed to have a 25% coupon on there.”

(No coupon popped up at the end of the transaction, meaning the coupon either expired, or she did not complete the sending process.)

Me: “I’m sorry, but a coupon didn’t pop up.”

Customer: *exasperated sigh, giving me a look of disgust* “Well, that SUCKS.”

Me: “I know, Sorry about that. The new coupon system can be a pain in the neck. Do you have the coupon anywhere I can see so I can—”

Customer: *cutting me off in a very rude tone* “You know what? Just take it! This f****** sucks!”

(The customer then flung the nail polish at my chest and stormed out of the store!)
