Re: The best way to stock up
'crawling under desks' - when I first started doing nights in TV Centre many years ago and the 2 TV channels closed down at night and everyone but the engineer went home - I was bored one night so I decided to clean up the continuity booths. They were both lovely brown colour throughout and with the lights on looked filthy. Under the desk I recovered about 100 pens - I presumed that if an announcer dropped one*, he or she deemed it too dirty and dark to find it and just got another one from the stationary office.
*As smutty as we all are/were, there is no euphemism intended here.
