(A male customer approaches the cash register.)

Me: “Hi, how can I help you?”

Customer: “What did you say to me?”

Me: “Um, how can I help you?”

Customer: “You…help me? How can you…help me? YOU?”

Me: “Um, yes. Do you have a problem with that?”

Customer: “You can’t help me!”

Me: “Okay, why not?”

Customer: “Because I don’t need YOUR help!”

Me: “Okay, what what do you want me to do? I’m the only one working here.”

Customer: “I want you to ask me, ‘How may I serve you?’”

Me: “Um, no.”

Customer: *cusses up a storm and leaves*
