What’s your point? Some an anecdote means that people working in the service industry shouldn’t earn a viable minimum wage? That they have to resort to essentially begging to earn a living? Tip culture is dumb, they provide a service. If they did an amazing job maybe add it on top. If they did it awfully, well complain, and it can work like any other business where someone is not up to standard.
What is your job? Software engineer? Do you want to be tipped for lines committed to git? Alleged higher skilled jobs you aren’t treated like this. Good human interaction does actually require skill. It’s not like some
glue programming job that can probably be replaced by a neural net.
