interesting story... was at Heathrow airport and had a hankering for a bagel and cream cheese, placed my order and proceeded to check out..... seven fucking pounds WTF! i didn't expect that. i thought to my self no fucking way I'm paying that much for a shitty bagel and cream cheese at least not today. so i did the classic "Scottish Hack" checking all my pockets pretending to look for my wallet and proclaimed that i had been robed and had no money to pay. they guy said to bad and proceeded to throw the bagel in the trash.
Ended up having a pint of Lager and a bowl of Irish stew charged to my CC $32 CAD after exchange and fees. last time i do that.
this leads to a bigger story where Large and Small business in Canada will start refusing to accept CC as the fees have become unrealistic.
