Forgive my bafflement, but why would such a policy be a problem here? (If memory serves me correctly, certain NYC restaurants also ask for a credit card in case of a "no show".) Whilst I realize it involves extra admin on the part of the resto if they actually have to process a "no show" penalty, surely it's better than absolutely nothing - particularly at peak times? To state the blindin' obvious, restaurants are a business not some sort of pseudo-charity. By way of an analogy, if you book theatre tickets to be collected at the box office and then don't pick them up, surprisingly you still have to pay for 'em. As Jeffy Boy expressed, surely the vast majority of decent diners would have no problem with leaving a credit card number. If diners have to cancel for unexpected reasons, then it also motivates those who wouldn't bother otherwise to call and let the resto know - and in a timely manner - rather than just think they can get away with the "my grandmother's second cousin's hamster's brother ate my car keys" school of excuses. Oh well, enough already! I've a Burns' Night supper to attend to and yes, I HAVE taken all my invited guests' credit card numbers.......
