Ruebensesque, I stopped at a gas station. I was turning in a rented vehicle, and needed to buy gas to make up for usage.
I thought two gallons would be enough, but didn’t stop the pump in time. I let it run to $6.66.
I went inside to pay for this. When the Asian lady behind the counter handed me my credit card, she pointed to the number…6.66…on the register.
“Is this your favorite number?”
