Yesterday I stopped at the corner gas station for a cup of coffee. The guy in line in front of me told the cashier he wanted to prepay for “half a tank.” The cashier thought for a moment and said “That’ll be twenty five dollars.”
“Twenty five dollars?!”
I probably should have minded my own business but I asked him, “How big is your tank?”
“I don’t know.”
It usually takes 10 gallons or so to fill my Corolla, and even then it’s nowhere near empty since the tank holds a bit over 13 gallons, so I said, “Let’s say fifteen gallons, so half a tank would be seven and a half.” I’d glanced at the price on my way in so I did some mental arithmetic based on $2.319 a gallon and said, “Call it twenty dollars.”
The guy thanked me, paid the cashier twenty dollars, and went out to pump his gas.
What I don’t get is someone thinking “half a tank” is a useful unit of measurement since cars have different size gas tanks. Anyway, gas is sold by the gallon, or more appropriately by the dollar, so “half a tank” doesn’t really mean anything.
If there’s a question in all this, it’s this: Has anyone else ever overheard a similar comment? I’m sure there must be some doozies. Thanks in advance.
