The issue there is the same issue that plagues sellers on Amazon or Ebay- brand loyalty is difficult to maintain when one operator often doesn't have the snack you want, or you can't find the operator in your area. Branding could help, but it's unlikely that most consumers will remember what operator their vending machine snack came from, just like I will never remember what 3rd party seller my Amazon product came from.

Isn't that still a branding issue?

Have a bright orange gorilla swinging by it's tail as the mascot. On both sides of the machine and on the front (though transparent enough to see the snacks without issue). "Wait, gorillas don't have tails?" you question. Exactly, that's the brand name: Gorillas Don't have Tails.
