Full Of Hot Air

(Propane can only be stored in tanks up to 80% capacity. This is because when the tank gets warm, the gas expands a little. Thus, we leave a 20% buffer.)

Me: “Hi, how can I help you?”

Customer: “I’d like to lodge a complaint. Your driver keeps cheating me on gas.”

Me: “Oh? How so?”

Customer: “Well, he only fills it to 80%.”

Me: “Oh, we only fill it to 80% to allow it to expand on hot days.”

Customer: “That’s bull-s***! I want a full tank of gas.”

Me: “We can’t do that, ma’am. If we fill it to 100%, the gas has nowhere to go when it expands. Your tank might rupture.”

Customer: “You’re lying. I want my 100%! In fact, since you keep screwing me over, I want a 120% filled in that tank!”

Me: “Ma’am, it is physically impossible to fill something 120% of capacity. We’d blow up your tank.”

Customer: “Then tell your driver to leave the extra 20% in a bucket beside the house!”
