Children don't get the tablet immediately, they eat without the tablet and get it when they are done, so there is plenty of time to chat, with opportunities for talking with the adult.

That being said, everything you say makes sense, but the reality is if you don't get a break every couple of months for a few hours, the parents don't perform, so from my perspective they (and myself) get a pass for the tablet.

As for the volume, they can lower it? I'm very careful making sure the volume is low, but I guess some people aren't careful.

This also assumes the children don't spend time with the parents. The parents could be spending many hours with the children so whatever happens at the restaurant is very small in the big picture.
