I love coffee. I would see state cops get coffee at the convenience stores, but they would never let them pay for it. I thought that was very nice, but the cops wouldn’t accept it.
However, when I would stop at the truck stops with my uniform on, they absolutely would not allow me to pay for my coffee, I guess because it was out of respect for being a pilot ? I never understood it, so I gave the money to the cashier as a tip.
Problem solved. Truck stop coffee is very good.
I once was given decaf. Wow! What a difference.
