If I am not required to do anything, I will not if I am uncomfortable with it or simply do not agree with it.
I principally refuse to pay by standard if service is not proper. If service is exceedingly well, I tip more. If service is good/standard, I round up the sum. I do not work with percentages because with large sums that is ridiculous for me.
You should deserve a tip and it seems that it has become so standard for people, they also feel entitled when they have given bad service. In that case I'd rather spend my money elsewhere and forget about an arrogant service provider who can't even provide basic, courteous service.
