In reply to 93EXCivic :
There are several different manufacturers of coin operated telescopes / binoculars. I believe my company, Tower Optical, is the only one that won't sell you the units. They maintain ownership of the machines and make a cross country tour once per year to make sure their agents, me, are taking good care of them.
Negotiations are made with each location in terms of what percent of the revenue they will get and I decide if it's worth my effort...high volume, easy access, somewhere I want to be, & low crime results in my being willing to give a little higher percent.
I'll stop there in terms of explaining what happens next between the parent company and myself as I'm a third generation employee and perhaps what happens with other agents is different.
Pro = This essentially is a vending business but unlike soda, snack, etc. machines, I have no inventory to manage, I just sell air and this allows me to operate out of my garage just using a little Mazda CX-3.
Con = My travel distances are much greater as I've got to go to scenic places that draw crowds...amusement parks, zoo's, piers, etc. I only do piers as I love the beach and it results in a very efficient route up and down the coast.
I'm a morning person so I have no trouble timing my departure so that I hit my first machines just as the sun is coming up, be parked at my final pier before they get crowded, and be home before my family is getting their day going.
I've never been robbed but I carry a monster screw driver in my hand at all times, plausible deniability that's it's a tool not a weapon, and I have been cased twice that I know of.
It's getting harder and harder to find banks that will accept coins...at one point, BofA demanded that I stop giving them coins in sealed, serialized bags, just open burlap, and immediately they started short changing me, a lot, like $30 to $50 per $1,000. I called the Fed's on them but my case never went anywhere.
I moved to Chase but after a few years, they started blowing me off saying their vault was full and I finally would up at little local bank, Union Bank, that has taken very good care of me for several years now but if they ever sour, I'm not sure what I'll do.
