My first thought was I hate it like I hate places which auto charge for tables over a certain number of people. I'm not sure why a table of 8 is harder than 4 tables of 2. Based on my experience most of the time the larger tables seem to tip a higher percentage anyway as everyone tosses in their yuppie bucks and walks away...although there are times where someone walks away without paying a dime (I'm thinking of a certain CP poster who did this a couple of years ago).
On second thought if it's 14% it sounds ok as I think I can count on one hand the number of times I've made a statement and left without dropping a tip. If there is a problem it's frequently cold food or undercooked food which isn't the servers fault...and often when this is brought up a manager will be informed and something on the bill is comped.
I'd like to have the option to select who I want to give the tip to or select percentages for each area. In the case where my chicken is undercooked or some other issue with the kitchen where the waiting staff deals with it efficiently I would want to ensure they get the bulk of the tip, some of it goes to the bartender, the dishwasher, etc but the cooks don't see a dime. Include a card with the bill where you fill in the amount of the tip and % for each area of the restaurant. If I don't fill anything in, the standard % gets paid out. To me this would show a restaurant manager where they need to focus their attention.
