Nothing Beats Budget-Friendly Oxygen!
A man walks up to the counter holding a helium tank rental and a pack of balloons.
Customer: “Hi, I need these filled, but I’m not sure how many the tank will do.”
Me: “Sure! That tank should do about thirty standard balloons.”
Customer: “Great. I have a hundred.”
Me: “…Ah. You’ll need three of those tanks, then.”
Customer: *Surprised.* “No, no, no, I thought I’d just fill a few of them halfway. That should stretch it, right?”
Me: “Halfway?”
Customer: “Yeah. Just enough to puff them up, not make them float. They don’t need to float.”
Me: *Pauses.* “You know you can just use regular air for that, right?”
Customer: *Blinks.* “…Oh.”
