Obviously not. I have close friends who worked as waiters (and even worse, in the kitchen), and they were getting $300/month on 12h of work with the promise of tips.

That practice really needs to stop.

Recently I went to a restaurant in Cluj that had an app from which you could do everything: see menu, order, send notes to the chef, pay

The experience needs to be polished a bit (low 4G signal and no wifi made this quite hard to use for me), but I feel that could empower waiters more. Maybe by getting paid the same for a lot less work, or by creating a completely different type of job.

Tips just need to die (as being counted a part of a salary). It's only a thing in countries with poor worker protection so here's hoping they get more of that. The only country I have seen it used in was the US. My wife worked as a waiter in Copenhagen and they got a good pay and few tips. They tips they did get all got put in a glass and shared between every single employee equally, the only way tips should be used IMO.
