Me: Hi, welcome to ****. How can I help you today?”

Customer: “I’ve been waiting here for 15 minutes. I want everything here discounted.”

Me: “Ma’am, I left here maybe two minutes ago, max, to check the fitting rooms.”

Customer: “Are you calling me a liar?”

Me: “In short, yes.”

Customer: “Bull! Do you have any proof I wasn’t here earlier?!”

(I point to the huge camera on the ceiling.)

Customer: “…”

Me: “…”

Customer: “I’ll shut up now.”
