At the school where I work, we have five of these (and they are not necessarily of the Xerox brand).
On any given day, one, two, or zero of photocopiers may be working. It is rare for all to work at once.
Every morning I join lines of frustrated teachers, waiting for their turn at a copy machine that jams, runs out of toner, or breaks down all together. I've witnessed teachers nearly coming to blows over people making too many copies, taking too long, or hogging the machine.
The school recently bought a photocopier worth thousands and thousands of dollars, and that's the very machine always out of service.
But I guess there's a machine of frustration in every place of business.
Have you ever been frustrated by business equipment--namely, copy machines?
