* Having AirPods in doesn't mean not listening. I just wear mine and have them on transparent. For particularly loud settings I use live listen.
* I would love if my server was allowed creature comforts like being able to listen to music or podcasts. Working in a restaurant that has the same 20 terrible songs on repeat is miserable. Service jobs are miserable, people suck, the less "masking" the employees do the better.
If the cost of labor is too high just get rid of the labor. It will be a hit with young people. The last thing I want is having someone waiting on me, if people weren't already used to it we wouldn't invented it again because it's weird. The best restaurant experiences I've had are seat yourself, get your own drinks, order on the website from the QR code at the table, and pick up your food from the window.
It's why "food halls" are doing so well.
I don't care about the staff asking me how my day is. I don't care how their day is going. I don't care about how "attentive" the staff is. I don't care if the staff has AirPods in. Replace the check ins with a call button. Familiarity with the menu for questions is all the interaction needed. Wait staff can be reduced, since they are just hanging out in the back unless called or serving food.
We can get rid of pretending the restaurant under paying the wait staff is the diners problem to be made up for with tips, because they need to employ people to talk to you while you're eating.
Extremely high end Michelin star places don't really have check ins, they just monitor you and do their explainers while they serve you. That is nice service, but most restaurants aren't at that level at all, and the prices at a Michelin place are so high that there is no need for a tip for the service.
Working during the restrictions was traumatic.
At least in the UK, a stressful and busy but ultimately friendly job was converted into playing restriction police. I'm not surprised that a ton of people just decided to sack the job off after that.
