More technology is not the answer to everything...

So, this morning I'm in a Giant grocery store. Giant is a chain of stores here in the mid-Atlantic region that I think belong to Stop and Shop. We go over to the deli counter and I notice that they have a digital ticket machine to say who's next in line. You know the ones that you pull the little tab and get your number. They put up an LED number behind the counter to say you're next. Now, I'm a fan of the take-a-ticket concept as they keep from fist fights starting at a pretty crowded counter but here's the question in my head...why does the ticket itself need to be digitally printed real-time? Did the pre-printed tickets not work? Just feels like the ultimate technology for technology's sake.
