Re: I just made my first Bitcoin ATM withdrawal... 3BTC from my printer.
If you are concerned about the private key, just take your receipt to your table/car and scan it with your phone and move to your own address.
So the waiter has plausible deniability if he is faster than you. Anybody in the room could have taken a picture of the receipt while falling out of the printer, spied on the electromagnetic waves the printer produced etc.
(Yes I'm one of those skeptics who think it is a bad idea to print private keys in the first place. Bitcoin are digital money. Printing them is a nice gadget but of no practical relevance in any future I can imagine.)
i disagree, if you want to have a critical mass using bitcoin you should try to think as the critical mass. humans want to have something in there hands and something what is easy to use. if i got 4 beers in a pub maybe i'm not able to use my mobile anymore...
