(I’m sorting out sizes in a rack of shirts that just gone clearance. I notice a customer that appears to be having difficulty finding what they’re looking for.)

Me: “Sir, I just want you to know that the extra smalls, smalls, and mediums are all in the labelled sections. However, I’m still in the process of sorting through the larges and extra larges. Let me know if you need help finding anything.”

(The customer randomly takes a bunch of mediums and throws them in the small section.)

Customer: “I don’t need your f***ing help!”

Me: “I apologize if I offended you sir, but it’s my job to offer assistance.”

Customer: “WELL, THEN YOU’RE NOT DOING YOUR F***ING JOB!”
