> can you imagine a bar where people are just supposed to drink and leave?

That is what a "bar" was invented to do. In the old public house, patrons would remain seated and the alcohol was brought to them. A heavy drinker would drink until they couldnt walk, but would still occupy a chair. Then the "bar" was invented. Patrons now come to the alcohol and will generally depart before becoming legless. A single bartender can now dish out far more alcohol per hour than any table server. That didnt exist as a concept until a couple hundred years ago.

Proper sushi "bars" follow the same pattern. You eat solo, often with curtains between individual patrons. You eat fast. Then you leave. You dont hang around for a chat.
