It's my understanding that you're only allowed to dispense tobacco in adult only designated areas, atleast here in the state of Texas. I've recently talked directly to the Texas Comptroller; I figured that it would be a novel solution for people who like to go to clubs and have ran out of cigarettes.
As far as the Hot food vending machines, I do mean refrigerated food that gets heated. I thought it may be an interesting concept for a large office environment; a company I had previously worked for had a micro market that would often sell out of frozen goods to eat, especially breakfast and afternoon snacks. I did a little research and found those Bicom Vending machines interesting.
Perhaps my ideas and vending strategies aren't the most thought out, however I think that those types of vending would provide solutions to things I viewed as problems. What are your thoughts?
