Picture a vending machine.
Glass front, spiral coils, snacks and drinks. You put in money, something drops, you eat it.
Now picture the same machine inside a factory. Except instead of candy it holds safety glasses, cut resistant gloves, drill bits, ear plugs, and cutting fluid.
And instead of money, a worker swipes a badge.
That machine was installed free by a supplier, sits on the customer's floor, and it is one of the cleverest things in American industrial distribution.
It sounds like a gimmick. It is actually a lesson in how to make yourself impossible to remove.
Come look at how it works.
