Apples and Oranges. The discussion on tip practices at restaurants was settle years ago. In the USA we tip. In Europe they do not.
Those are the rules established, polite people live by them. Those who choose not to deserve to be excluded from a restaurant at the owner's choosing.

I do a lot of traveling around the US. The rules are different in different areas. And they are not laws. They are rules. Although I tend to abide by them. If I get lousy service, I will take advice I got from a guy over three decades ago: I tip a dime.
Rules change, btw. That is what those who put tip jars at dry cleaners, Starbucks, et-al are banking on.
I think our economy is changing the tipping rules. In my case, the restaurants have ceased getting my business, for the most part.
