Use critical thinking. No you don't cycle down a list. You say "hey I think your passport might have an extra letter r in it, you have another credit card, medical card, etc. I can take a look at?"
If anyone with a brain really thinks it's a forged passport they would skip straight to the whole "denying the transaction" part and reporting it through the banks reporting system.
This whole thread is a mind fuck of really dumb opinions. The cops just should not have been called.
I would feel the exact same way, but there is one thing stopping me. These companies then use my money (and others) to fund super pac's to lobby congress and buy politicians to enact legislative I think is morally and socially bankrupt. When companies can no longer do this, I think that's the day business becomes less political.
