Tourists in Belgium can't seem to get enough of the beer there - and they're pretty big fans of the glasses it comes in too.
It seems that the more beer some tourists drink, the lighter their fingers get and a lot of beer glasses, despite not being included in the price of the beer, are getting the five-finger discount.
Bars all over the country have been trying to fight beer glass theft, in whatever way they can, as thousands of glasses disappear every year.
In Bruges, Philip Maes, owner of the Bruges Beerwall cafe, told the Guardian he has lost "at least 4000 every year".
"The tourists liked to walk with them. For some reason, some customers think that when they pay for something to drink, they get the glass as a present," he said.
The bar owner has resorted to high-tech security alarms attached to the stem of each of the glasses, an expensive solution to an even more expensive problem.
