On my way back from Blythe I stopped for a shower at the Flying J in Ehrenberg.
The cashier asked, "Do you have a rewards card?"
"Are you a professional driver?"
At this point they usually ask for twelve dollars. Instead, he got on the intercom and said, "Eric, my computer shows showers 3 and 14 are available. I'm sending back a guy in a gray shirt with a white beard. Give him one of those."
"Why, thank you."
Eric directed me to shower 14.
This has happened five or six times before. Or a trucker in line behind me will offer one of the free showers he'd accrued with his rewards card. There are nice people in the world. I left a tip.
