Customer: “Do you have butane?”

Me: “Butane?”

Customer: “Yes.”

Me: “Butane, like the gas?”

Customer: “Yes, it’s for your skin and hair.”

Me: “I’m sorry, but I doubt that’s safe. Butane is a type of lighter fluid. I am almost positive it is not beneficial for your hair or skin.”

Customer: “I use it all the time. I swallow it and it works. Butane.”

(Puzzled, I look at the woman for a few…and then it hits me.)

Me: “Do you mean biotin?”

Customer: “Yes, butane!”
