Let's be fair to this error message. Its not for a techie, it's for the customer who has come up to get a drink to tell them it can't serve them. Otherwise what else is meant to happen, it says nothing on screen and the customer gets frustrated because nothing is happening?
This isn't even a Windows error message, aside from the fact you can see Windows is present this really has nothing to do Windows. It's an error generated by the software running the vending. Not quite what I expect from the bork column to be honest. OS errors interjecting into customer facing applications is usually what's funny about these contributions.
