We ate at Doolittle's for the 2nd time tonight. After eating there a few weeks ago we decided to pick it for our monthly dining out group. Again the meal was good, but I was shocked by the automatic 22% tip, since we were a group of 10. On top of that the tip was calculated on the total including tax. I never tip on the amount including tax, nor should anyone else. I understand adding an automatic tip for large groups, but the service didn't merit 22%. It would be a better policy to add an automatic tip of 15 - 18% and give the customer the discretion to decide if the service merited an additional tip. Tonight's service was good but not stellar.
