They're legit, and they make big tips when they work hard.

I have worked as a tipped employee, and I have never heard a tipped employee say “wow that table/person didn’t tip much, I should have worked harder”

s/they work hard/somebody decides to tip which may or may not reflect any effort the worker put in because some people just don’t tip and depending on tips is a shitty way to scrape by/

The comment I was referring to was talking about the UK, where we don't have a tipping culture in the same way the US does.

>They're legit

It is hard to know whethr they are working legally.

Oh, I thought you were talking about the establishments themselves, sorry!

I can confirm they wash your car if you pay them to. Is that legit enough?

I was referring to the parent comment "The official narrative here is modern slavery with undocumented migrants". Some of the people working in these hand car washes may not have the legal right to work in the UK, which makes them ripe for exploitation.
