I haven’t heard of a service charge before but it would deter me from eating there.
We ate at a restaurant in Orlando last weekend and they did the service fee thing. It was 18% on a $100 bill. I had to pause to think about it. In the end, I put a $10 bill in with the receipt.
I’ll bet a lot of people won’t notice it until people start asking questions.
I’m a creature of habit and tend to frequent the same establishments repeatedly. Tend to know the waitstaff personally and tip well as a result.
Also as a creature of habit there are restaurants where I have always ordered the exact same thing every time. Some don’t even take my order. They bring my drink and start cooking. Always a nice tip.
