There are two issues that come up reasonably often at our restaurant and we always end up sort of winging it. I'd like to come up with a consistant policy and would like to hear the opinion of all you regular diners out there.
#1) Customer takes both copies of credit card reciept. I've instructed to waiters to say, "Please sign and leave one copy for me and feel free to take the other for yourself." Despite that, some take both and the waiter is left to determine what the tip should be.
#2) The amount of money the customer writes down in the tip space and the amount they write down in the total space don't add up.
My inclination for #1 is to simply auto-grat the table at the same rate that we apply to large parties (18%). My inclination for #2 is to assume the tip is accurate rather than the total.
All that said, I've heard more than one person on this board complain about restaurants that don't clearly state gratiuity policies on their menu. We do mention the bit about large parties but don't want to turn our menu into a list of disclaimers.
Anyone out there a) have a problem with my proposed solution and b) care if I don't bother to mention it unless questioned?
