You go to a sit-down restaurant:
1) You wait 30-60 minutes to be seated. If it's a really nice restaurant, you may try to make reservations. Nah, nobody does that anymore and the online things are booked a week in advance (Downtown Seattle, I'm looking at you). Nah.
2) If you manage to get seated, the clock has started. They want you in and out in under an hour. The waiter will show up typically just as you've sat and take your drink order, you will see him again in 5 minutes to take your entree order. In some places, you will not see him again until the bill, as food is run out to you by runners (door dash, but indoors). In most cases he'll appear as you're eating to see if they missed anything, hoping for another drink order (if they serve alcohol). Otherwise he's gone until he thinks you've had enough time to eat, and gives you the bill. Whether you're done or not "No hurry!" he hurriedly says. Frequently it's pay-by-QR code, even in nice, expensive places, so you'll never see him again. But he'll come see why you haven't left yet and take your card if you don't do that. Then you're expected to leave. If you're sitting with friends and talking, at some point they'll try to move you to the bar so they can turn the table over. If not, they'll stop by to "anything-else" you until you take the hint.
3) For reasons I don't understand, it's trendy not to leave the ceiling support exposed, offering no sound-proofing at all. The place is deafining, it's impossible to carry on a conversation in a busy place. This is probably the point, see #2.
4) If the sound-proofing isn't enough, it's also trendy to play music too loudly. It's nice to have some to wash out the din of clanking plates and masticating, but again, if you want to talk to people, it's almost impossible.
5) "Not turning a profit" is not the same as not being able to pay your staff and your bills. It means the owners yacht payments may get missed. I'd be very slightly empathetic if the owners of restaurants were at all involved, but in most cases they're not in the picture using managers to run the place, it's just a "property" in their "portfolio".
Restaurants, and honestly a shitload of other businesses, need to be reminded that they exist to serve customer needs. If they're not meeting those needs, someone or something will rise to answer them, possibly to their detriment. Figure it the fuck out and get on our level.
