A Belgian man who ordered a burger from a McDonald's restaurant was amazed to find £10,000 cash in the same bag.
Marco Parra-Martinez, 23, ordered his meal from a McDrive restaurant in Waterloo, reports Het Laatste Nieuws.
Inside the paper bag, as well as his burger, was an envelope containing 15,000 euros, the equivalent of more than £10,000.
"I hesitated one moment, asking myself if I shouldn't keep the money," admitted Mr Parra-Martinez. "But my parents taught me to be honest at all times."
So he returned the envelope to the restaurant.
McDonalds said the cash was restaurant takings that had accidentally been put down next to Mr Parra-Martinez's order. They promised him a reward for his honesty.
