Leave it to the Matkahuolto bus company to make the holidays fun in Finland. Embracing the holiday spirit, it allowed passengers to pay for one-way trips with gingerbread cookies. The only stipulation was that the cookies had to be decorated to show their origin and destination. They also had to (obviously) to be edible.
As expected, the response to this unique offer was overwhelming, forcing Matkahuolto to deny passengers once it had given away all free tickets. This culminated with #piparigate, a rough tranlation of "cookiegate," which led to protests. It was cute idea and fun while it lasted, but everyone had to know it wouldn't last for long.
