Yesterday , I went to there ate lunch with my family, sometimes we go there feel not to bad. But this time I found there something change was about payment , they change the machine you must choose one of the tip on 15%' 20% and 25%. we knew normally gave 15% is befor tax, but they set after tax, and they didn't mind service is good or bad you all need pay less 15% tip . Unfortunately they service change bad , let me felt not good, if they service still good , I will pay, but they didn"t keep high quality, and also to force customer pay high tip after tax total amount....
