Hungry for McDonald's but short of cash? No problem, if you live in Sweden.
The fast-food restaurant chain has rolled out a green festival campaign, in which it is accepting empty cans as a form of currency in a bid to get people to clean up their act.
McDonald’s stores, mainly near festivals and green spaces, are hosting billboards announcing it accepts "cards, cash, and cans."
A clever twist is the billboards also dispense black plastic bags for revelers with a printed "price list."
For 10 cans, hungry festival-goers can cash in on a hamburger. Those with more of an appetite can swap 40 cans for a Big Mac. Yum.
