I have to agree. This is not at all mandatory... A tip is when you were so pleased with service and wanted to give the waiter or waitress something extra. My opinion is!!! Service charge??? that is the tip... they can phrase it anyway they like, but added money to the bill for service is just that. And there have been more time than not, that we got horrible service. This issue seems to only bother americans. I could be wrong, but any tipping is not a have to do thing.... If your eating out a lot for a long period of time, this could become a huge burden.. But that's my opinion. Service added is just that...
