I agree, but restaraunts all over the world use “hidden” ways to subsidize lower prices.

For example here in Belgium, they don’t give tap water and force you to buy bad bottled water at a 300-1000% markup (so much so that beer is often cheaper) in order to be able to post lower meal prices. But people here are stingy as fuck and will in the same breath complain (and write bad reviews) about restaurant prices being more than supermarket prices as well as that “the staff is all students/not enough staff”.
