This is a most excellent place for technology news and articles.
TL;DR - Instead of locking shit up in a cabinet you need an employee to open, dude wants to use vending machines (that he sells) so you can just buy the stuff without waiting around.
Honestly not a bad idea. Trying to find the only employee with the key to a locked cabinet is fucking annoying and wastes so much time. They often have a call button, but in my experience nobody fucking comes anyway
Useful unless you just want to look at the item more closely (read the back of the box or whatever before you purchase.
