Gas station attendant: How much?
GSA: How much gas do you want?
Me: Um. Fill 'er up. [I cannot remember the last time those words came out of my mouth.]
GSA: Cash or charge?
Me: Oh, credit.
GSA: There's a five-cent discount for cash.
Me: Is that already in the price?
Me [who just has to tell everyone how to run his business]: That would be useful information to post there. [I point to the price sign that you see from the street.]
GSA: Oh, it's there on the window.
Yeah. In small print. And you have to be stopped at the station and looking at the window to notice it.
Me: You don't want it out here?
GSA: It's a secret.
GSA [looks at pump, which says $35.68]: $35.
GSA: The discount.
But I do the math later and he has given me six-cent y pico per gallon discount. Maybe he hates making change?
