Danish chocolate brand Anthon Berg opened the world’s first chocolate store where you can’t pay with cash or credit cards, just good deeds. Instead of cash registers, people have to pay at iPad stations. Logging into their Facebook accounts, they’ve got to post the promise of the good deed on the walls of both the giver and receiver of the deeds. ‘Don’t comment on your girlfriend’s driving for a week’, ‘Serve breakfast in bed to your loved one’ and ‘No talking behind your girlfriend’s back for a month’ are among the most popular. Hardly anyone selects ‘A week where you don’t lie to your father’. I wonder why.
