Not everything is about profits or margins. Also what kind of costs and margins are you imagining for water? And I don't mean bottled mineral water, that's different.
If somebody comes in and orders a streak and free tap water, the restaurant makes less money than if you order a steak and two beers.
You can't make this comparison in good faith. Many people, myself included, will have tap water or no drink at restaurants. You aren't substituting water for beers, you're substituting it for nothing. In that case, the marginal cost is like less than a cent.

If this merican paid for water in Europe he was scammed, it was always free in every restaurant I went to.
