Customer: “Do you have a charger for this battery?”

Me: “We have a universal charger, which should work with it. It charges 90% of all batteries.”

Customer: “Could I have one which charges my batteries to 100%?”

Customer: “Do you have a 72mm lens cap?”

Me: “Yes. We do.”

Customer: “Is it a 72mm lens cap?”

Me: “Yes, it is. That is what you asked for, right?”

Customer: “Yes, but is it a 72mm lens cap?”

Me: “As I said, yes it is.”

Customer: “Are you sure?”

Me: “Actually no. It’s a 55mm but bring your camera in. I have a hammer and I’m sure I can make it work for you.”
