Where can I learn the ins and outs of having my own vending machine business?

It is important to do a great deal of research before starting any business. For a vending machine business, gumballs.com has a good starting guide for people considering vending machine routes. One might also talk to other vending machine operators to get experienced advice. If you don't know any owners, try calling the number on a vending machine to see if anyone will talk to you. Many vending machine businesses are run by individuals rather than large chains, so you might get the owner directly. Before starting a route, be sure to know how well traveled it is and by whom so that you know if you're likely to earn sufficient income from it.

What if your drink doesn't come out of a vending machine?

Either the machine wasnt filled/loaded properly in which case you just gave Coke a nice donation because there was nothing to vend. or The product is stuck in the machine and generally gets released when someone else tries to vend that product but it may not necessarily be the next vend, it could be two vends later meaning the third person to use the machine will get 3 Cans/bottles depending on which product you were trying to get. Why do I know this? I know it because ive seen a machine being loaded so I know how they work and because we have a Coke vending machine at work which does this all the time.

How do the inner mechanics of a vending machine work?

Saw one yesterday. I think this is how it works. Inside the vending machine, the items are organized in some kind of shelves or rack, or whatever you want to call that. Items are organized in that. Next thing we know that there's some kind of "lift" that will work and pick up the thing that you want. The "lift" will move up and down, left to right. and then drop the thing to the box where you pick it up. of course behind the rack of every column of item, you can find some kind of centrifugal stick that will give a force enough to make one item to be pushed into the lift. Well, this is my analysis after seeing an open drink vending machine yesterday.
