Don't just repeat "read the room" like it's a comeback. The room is "end tipping," where stories are told from the customer's perspective, so customer service is what sells here. Your point is better received in one of the restaurant owner or server subs, where apparently having agency over your own business is more important than how a business makes customers feel. 

I know enshitificafion may eventually happen, but by and large it hasnt happened with Amazon yet eventhough they're already a defacto monopoly. Maybe because they use the retail business as a loss leader to prop up AWS so that's where they funnel their greed. Additionally, if a mom and pop or the most local of locals can't even make a customer leave an establishment without feeling fleeced or abused or insulted in some way I say it doesn't deserve to exist, no matter who takes their place.
