Thanks to a sale on french fries at McDonald’s in Japan making those salty sticks of potato goodness a lot cheaper, local kids started throwing what are known as “potato” or “french fry parties” — which, according to Gawker, is basically when you buy a ridiculous amount of fries and spread them “feast-style” across multiple trays and dig in with your friends.

Apparently, the people who work for Mickey Dee’s Japan aren’t fans of those so-called “Potato Parties,” which cause huge messes for low-wage workers to clean up, and besides that, leaving uneaten food behind is considered wasteful, and highly disrespectful in Japan, even if it is a fast food meal consisting solely of french fries … so it is customary for you to consume all of your fries. Every single one of them.

But unlike their Japanese counterparts, the Korean kids paid a lot more for their fries, since there was no discount. According to one report, they spent as much as 270,000 won (or around $250) to host their Potato Party.

Having had enough of their shenanigans, McDonald’s workers eventually threw the Potato Party attendees out for “causing trouble,” so the party did end on a sour note, but the kids were still able to keep this memento of their epic meal:
