I ate out at a restaurant a couple of weeks ago. When I paid, the card machine declined the payment so I tried again and it went through. I've since discovered both charges were taken. The restaurant (a big chain) have stated they can't investigate unless I email them my bank statement showing both charges. Without printing and scanning back in (which I think would look dodgy) I can't think of any way of hiding the rest of my information and I'm pretty pissed off that they're not just checking their own records (which will show two payments from me in minutes) rather than asking for personal data.
