Don't fool yourself. "hire a manger" is insanely challenging. Also, your going to need 2-3 assistants(vacations, lunch,days off etc) and what happens when he threatens to quit. Also, you don't walk in day one and start making money hand over fist.

The reason franchises work is because they vet 99% of the owners.

Most franchise owners work long long hours inside the restaurant. The idea of a hands-off owner is a non-starter.

Yep, and they own & work multiple franchise locations. The margins are insanely thin that you'd be lucky to support yourself and a GM at every location.

Maybe a Subway franchise, but having employees that require self-provided functional vehicles, of which the business owner is liable in the event of an accident during working hours, seems "stressful".

I hope you're joking about the whole stressful thing there.

If you own the business, of course it's going to be stressful, on top of that, you are talking about a sect of hospitality that hires untrained and junior staff with sharp objects, hot surfaces and dangerous chemicles. There isn't much about that, that I can consider not stressful haha
