American tipping culture is bullshit. And to start with 30% is just plain stupid.
But not tipping at all is bullshit. I really need the taxfree money to buy drugs to cope with how fucking annoying and disrespectful half of all my guests are.
Id wish to be paid enough to not need tips, but to afford that my boss would have to raise the prices and other venues would snatch the costumers.
Just tip cash (5-15% is enough in most of europe).
This reminds me of that reddit post with the CO2 leak.
