(I am working on a till that frequently has problems with the scanner. I attempt to scan a customer’s item, but the barcode won’t go through and I mouth a swear to myself.)

Customer: “Go on, say it.”

Me: “Sorry?”

Customer’s Husband: “What did she do?”

Customer: “Swore under her breath.” *turns back to me* “You can say it. Vents the frustrations!”

Me: “I’m afraid I’m not allowed to swear in front of the customers.”

Customer: “Shall I say it for you?”

Me: “If you like.”

Customer: “Bugger!”

Me: “Ah, I feel better now.”
