… is a very helpful term.

Especially when the toner runs out mid-run and you find the cartridge you thought you had on standby is the one that’s just run out.
Especially when the courier bringing the replacements neglects to take a few extra steps to the office door and, in stead, leaves a “Collect from Post Office after 4:30pm” ticket.
Especially when you are as far as possible from the office phone when it rings – you race to get to it and pick it up just in time to hear a fax tone.

I’m sure I could go on, but my blood pressure’s high enough!
