So which is it? Do you want fake civility or sincere rudeness?
Germans are already different by the way, my German colleague was a bit shocked when he had a hair cut and one colleague walked in asking if he tried to do it himself followed by another asking if he fell down the stairs. It’s camaraderie, I guess mostly in younger people. Honestly his hair wasn’t bad at all.
as a bussiness, you are basically asking for a handout to make the lives of your waiting staff bearable. In my opinion this mean you should not run a business.
Why would i tip someone when they do their job? Should we do this for all jobs? (the same goes for the military in my opinion).
However, I've followed the debates occuring in the USA as a handful of restaurants have experimented with no-tip policies, and I am now really ambivalent about the practice. Several restaurants with owners who sounded very committed to end tipping have returned to it; I've read remarks from many waitstaff who say that they prefer and can make far more that way than they would ever be paid on a salary.
I don't think there's a clear answer. My gut still tells me that it's a bad idea, but I do not want to ignore stories from those actually working in and around businesses where this is a thing.
Having said that, I strongly suspect you're correct about that, though I'd also guess that personality traits are also a very important component, and those are also not handed out "fairly".
