That’s not “Passive” income, if you have to attract 50-60 people per day, pretend to interview them, while subliminally encouraging them to use the vending machine. That’s called a full-time job, and probably illegal, too.

And that isn’t $300/day profit, he has to pay for those items in his machine. The profit is probably no more than 50%, so $150/day. For an 8 hour day, that’s $18.75 an hour. That’s a lot of work for not that much money. It certainly isn’t “Passive.”
