Yeah, there is a lot of shadiness going on these days. I don't think tips should be requested in any sort of transaction where the employee gets paid more than minimum wage. Restaurants always had this weird system where you could avoid paying your employees if they were tipped, so it was drilled into everyone's head "you're stealing from poor innocent workers if you don't tip 20%". But this is not the case for most workers, and so tips should be truly for exceptional service in cases where the job position is on a normal pay scale.

This isn't to say that I don't tip when not required to or that I only tip people I think are being underpaid, but ... things have gotten a little out of control. If I feel like tipping, I'll tip. I do not need a prompt suggesting anything when it's not coming out of the employee's takehome pay.

I hate to say it but I think some government regulation is required here.
