Trolley Folly

(We have ordinary trolleys as well as flat-bed trolleys for large items. The flat-beds are supposed to be pulled along as the steering is in the back wheels. We tell customers this when we see them struggling. On this day, my coworker notices a lady heading out of the store having a lot of trouble pushing her flat-bed trolley.)

Coworker: *with a smile* “Those trolleys are a lot easier to pull along behind you, ma’am. The steering is in the back wheels. You’ll find it easier if you spin it around.”

Customer: “No! The customer is always right! I’m so sick of people telling me how to push my bloody trolley!”

(My coworker had not had any previous interactions with this customer, so her outburst was completely out of the blue!)
