Anecdotal example: A few years ago, my workplace at the time (a bookstore near a university in NYC) decided to try that payment method Square used to have that let you check in to Square when you enter a store and then just "pay with your face" or whatever. Sounded neat, I knew some folks who loved to pay for things that way in NYC at coffee shops and such, and the Square rep told us about all the other places near us that were adopting this. So we figured what the hell, jumped on in, got some iPad bundles from Square to use for this, and I was tasked with setting it up. Just a few weeks (!) after we had set it up, Square discontinued that service. Needless to say, ever since then, that bookstore has been very apprehensive about "new tech". Why bother investing time and effort into something new if it could vanish at any moment?
