Just wanna throw it out there that if you like this kind of thing, the best way to get more of it is to make sure the creators get paid. I *know* there’s some folks out there thinking “$6K/month, they’re living large!” but even for two people + associated other expenses, $6K/mo, depending on where you are, can be…

OBviously. But these are minimum wage jobs that barely pay enough to ensure that people can pay their bills at the end of the month. Tax evasion by the working poor is not the problem when so many rich CEOs offshore their salaries to tax havens.
I’ll keep tipping in cash. 

You didn’t include it in the story, but c’mon, the #1 reason these folks prefer cash tips is for tax evasion. 

Counterpoint: For old school delivery joints (think pizza, Chinese, etc. and not GrubHub/Postmates/whatnot), the person who makes the food isn’t usually the same person who delivers it. I’m of the opinion that the driver deserves less than the person who made it.
