This post is in a kind of reverse-engineering whereas, you get a solution before the problem is disclosed. You read both posts and then decide yourselves what is right and what is wrong. Confused, you will not be after the posts!
My advice to every operator no matter how big or how small should without hesitation speak to all of their respective/current sites and ask them if they would like any further machines.
What does this mean?
If you have a sweet machine, ask the owner if they would also like a toy or Pringles machine.
This will save you any unnecessary problems with any other operator who muscles on your patch with another machine because at least you will know if they really do want another machine and avoid any disputes with another operator.
Cheers
