One was a very nice Italian in Little Italy, they added c15%, which I probably would of added anyway.

the annoying one was over 26% at a sports bar on 9th Ave on a $18 plus tax bill for a simple burger and a beer.

I fail to see how anyone can justify a compulsory 'tip' of over 26% for such a simple combination.

If I am given exceptional service I will give a tip, of an amount I feel appropriate, however it is for me to decide if and how much I leave as a tip.
