I read a lot http://xnxx.in.net/xnxxjapanese/ Xnxx Japanese Merchant’s pay a 5% fee for accepting AMEX cards ( which could be different depending on the country of use). If my friend sees the AMEX logo in a merchant’s shop and he finds something that he needs, he then pulls out his AMEX card and asks if he can get a 5% discount by paying in cash.
