Story Time:
I tried to purchase the uniform/shirt from a Taito Game Station employee when I visited Japan (was red/white with "TGS" logos/space invader).
I don't know if it was a language thing, but I kept trying to tell her... "I want that shirt, tell me how much"
She answered "sorry not for sale"
So I said again "Everything is for sale, how much" she just looked confused.
Seems like we could have come to an agreement, I mean I might have paid 200$ for it had she understood bribery.
