Pachinko is basically Japan's version of slot machines.
And really this should be renamed to 'don't have change for pachinko, messes with coke machine to get change and plays with old lady who thinks fursuits are cute, and then goes to play pachinko, only to find out it doesn't even take yen. Then some staff come over to tell us we're not allowed to shoot in the building'.
But that title was far too long.
