I've been eating in restaurants from street food to nice ones on multiple countries, and continents. Service fee (and taxes too BTW) are always included in the list price. That's the default

What kind of shithole country you're living in?

Edit: since servers in USA are paid hourly (even if shitty), the service fee must be in the list price. it's just the fact that the servers are not paid enough, and the customers are being blackmailed to pay extra off the books
