No Entry

You're in a room full of technical people dressed in white coats. They are packing computers into boxes. One of the technicians spots you and says:

'You shouldn't be in here. Every six months or so we come in and change all the computers, because that's all the time it takes for them to become obsolete. It's no secret - I'm sure everybody knows it - anyway, there's nothing here that can be of use to you. Sorry.'

You turn round and go back out the door, then make for the street door.
