The two tourists were vacationing in Sweden's capital in June. One night, when their dinner bill came, a big red stamp at the bottom of it indicated that a 20% service fee was not included, according to newspaper Dagens Nyheter.
Tourist, Paul Eller, says that when they asked the waiter about it, the reply was that in Sweden, restaurants choose if they want to include the tip.
"But that's not true," says a now enlightened Eller. "In Sweden, the tip is voluntary: it's completely up to the customer to give if they're pleased with the service."
He alleges that the restaurant tried to take advantage of him, because he was a tourist.
