Restaurants that tell you when to leave as you’re sitting down

Look, I get it…the bane of every server is the 2-4 top that camps out over two hours (and usually doesn’t order much and tips even less). But geezus there has to be a better way to encourage diners to not linger past the 1.5/2 hour mark. This post-pandemic trend of telling people when they have to leave as they sit down is really weird. Most people are done with their meal at this time normally without having it imposed upfront. It seems unfair and awkward for the host/hostesses and servers to have to gate keep people this way. There must be a better, more subtle, and practical solution than making people feel like there’s a stopwatch on their table.
