(I am serving a father and son.)

Me: “Alright, here’s your club and your golf balls. Just follow
the purple path throughout the course.”

(Five minutes later, they come back to the register.)

Me: “You’re already done?”

Customer: “Yeah, I did hole number 5 and my son did hole number 16!”

Me: “You know you can do all 18 holes, right?”

Customer: *very serious* “You’re kidding.”
