Ive worked basically every position from busser and expo all the way to exec chef and gm and am currently a bartender. I can sayy with first hand knowledge that wages go down when switched from a tipped system to a non tipped system.
I guess first hand knowledge of the industry counts for nothing when a bunch of tech bros on lemmy know more than me.
Edit: makes me sad that people who want worker reform would want to support owner suppression of wages.
I know it doesnt fit your neat little box, but it is facts.
