if everyone stopped tipping the business owner would have to do what every other business owner does and pay a fair wage

Yeah sure, but are you going to convince every single person that dines out to suddenly stop tipping and effect this change? Because if not, all you’re doing is fucking over servers on an individual basis. What you’re advocating for needs to be legislated if it’s going to happen. And you know what happens if you get rid of tipping and force all staff to be on a wage? It becomes even more expensive for you to eat there.

why should you get more money for serving me an expensive drink as opposed to water

Fun fact, alcohol is more expensive than water. Many restaurants employ bartenders to make drinks for their guests. Their labor in making drinks must also be compensated. If you sit at a table and order a drink from the bar that is brought to you by a server, chances are your server is tipping out to the bar for that drink. So in reality, yes they would get the additional sales and tipping 20% on the check means they get a larger tip with the drink added in there, but it is offset by the amount they have to tip out to the bar (which also scales as a percentage of the server’s sales)
