(As I am working in the department, refilling betta containers, dressed in company attire and name tag clearly displayed.)

Customer: “Do you work here?”

Me: “Yes ma’am, I do. What can I help you with?”

Customer: “I was standing here for 10 minutes, waiting for someone to help me.”

Me: “Oh, well I have been here for the last 20 minutes.”

Customer: “Could you help me find this [competitor's can of cat food]?”

Me: “I am sorry ma’am, we do not sell that brand here.”

Customer: “DO NOT TELL ME THAT, I WAS JUST HERE LAST WEEK AND BOUGHT IT!! I KNOW YOU SELL IT!!”

Me: “I’m sorry, we don’t.”

Customer: “FINE THEN, PROVE IT!!”

(I turn to the back of the can and read it.)

Me: “Marketed and sold by [competitor]. Anything else I can help you with?”

Customer: *turns and walks away*

Me: *smile*
