I got suckered by this Tea scam. They asked for Y750 (about $112) at the end of it. So I paid it -- was about to pay with cash when I instead pulled out my credit card and smiled and said 'no problem'. Took the receipt, went home, photoshopped it to say Y75, then faxed it over to the bank and claimed I'd been overcharged! Bank refunded the difference within a week.

One scam meets another ...
