Customer: “Hi, do you have any safety vests?”

Me: “Safety vests?”

Customer: “Yeah. Safety vests.”

Me: “Like the ones that are neon yellow with reflective stripes?”

Customer: “Yes! A safety vest! Are you an idiot?”

Me: “Uhhh, no sir, but we’re a science fiction bookstore. You’d want a hardware store for that kind of thing.”

Customer: “Well, why DON’T you sell them?”

Me: “Because we sell books.”

Customer: “Well, you should!”

Me: “I don’t think many of our customers would normally want a safety vest when they come into a bookstore, sir.”

Customer: “Well, I did!”
