Who ever said doing a good deed can't be fun?

After a night out of drinking, William Armstrong accidentally lost his driver’s license somewhere on the streets of Cheltenham, England, according to Metro. Lucky for Armstrong, someone was nice enough to turn in the I.D. instead of taking advantage.

However, the good samaritans also took the opportunity to play a hilarious prank.

A staff member at Flight Centre, a travel agency in the U.K., found the license, and decided to return it via mail, but with a fake travel itinerary for a first-class trip to the Maldives. The phony bill racked up £5,000 (over $6,500 USD).

Of course, not intending to give Armstrong a heart attack, the Flight Centre staff also included a note that stated the bill was just a joke — and added that hopefully he’ll use their travel service next time he plans a trip. We’ll see about that.

The note read: “George, We’re just kidding. We’ve found you're [sic] driving license (enclosed) outside our shop and thought you might need it! Just make sure you consider us for your next holiday. Take care!”

As Metro noted, Armstrong’s middle name is George. He also tweeted out the fake itinerary and note.

Hopefully, he’ll keep track of his things in the future — or the next big mystery bill he gets might be real.
