The money I have has been hard earned and my pension means that going out for a meal is a rare occurance. I decide what I chose to do with my money and no one else. So if I decide to go out for a meal, I always expect to include a tip to the staff. BUT it is my money and I will decide, give a bit extra when I feel they have been exceptionally helpful, and like to thank them verbally too for their efforts. I dislike the automatic addition of 10%, for several reasons. Firstly how do I know that the staff actually get that tip money and how is it divided between kitchen and waiting staff? If the service has been poor, why should I be paying them extra? It seems to me that in those rare cases I should not be paying and in addition should be deducting 10% for the poor service. To think that you should pay even more over the odds with your change is absolutely not acceptable and is quite cheeky in my view.
Also it is clear that some people have plenty of money and have no problem spending extra and implying that other people are mean. I most certainly would not expect to give another £4 on top of the tip etc, and would probably not return to that restaurant if I felt I was being manipulated into giving more. However, as an ex teacher and being someone who will not be shoved about by anyone, I would certainly stick to my guns and tell them in no uncertain terms that I was waiting for my change. It is my hard earned money and I will not be manoevered by anyone into doing something I do not want to!!! To me , as it was meant to be, a tip was for effort over and above the work that they are paid for.
