I'm not sure if this topic is appropriate here but I'll give it a whirl since it happened when I tried to book a resto in SF last night. I was told that I had to give a credit card to hold the reservation. Nothing would be charged to it unless I failed to honour the reservation, or cancel it within 24 hours. I know that people do not cancel resos they can't make (which makes me pig-biting mad!), but I still passed on the restaurant and booked elsewhere. I have neve had this experience before. Is it common in San Francisco? Was I wrong not to give my cc? Other thoughts?
