Having lived in Austria for 27 years and in the USA for 25 years, I find the system in the USA a better approach to customer service for both the employee and the customer (and maybe the employer).
It’s more expensive for the customer (but “hidden” from the official price list, like taxes, hence it psychologically doesn’t look very expensive vs. Austria/Europe) but the service, in general, is *WAY* better. Like on an other planet better. Vienna even prides itself on their “grumpy waiter” culture. And so does Paris.
And while the official wages are ridiculously small, a 15%-20% cut of revenue is a super sweet deal that a European waiter can only dream of. My niece is one example who barely made a living waiting tables in Austria but is doing really well financially here in Dallas (and yes, she is smart enough to be (fake) friendly to every customer and makes (real) sure that the customer is happy because 20% of revenue $$$$$).
