Is it a boy thing? I've just moved into a desk previously occupied by a bloke and it's all coffee stains and sticky fingerprints. Hasn't he heard of DESK GERMS??? There's an urban myth going round that it is healthier to eat your lunch off the toilet seat than your desk. Not my desk, of course - thanks to those ponky sterilising desk wipes.
And don't get me started on EAR GERMS. When are they going to invent a mobile phone that doesn't get greasy ear germs when someone's been using it? Of course, my desk phone got the ponky wipe treatment too.
(not that I plan on eating lunch off the phone, you understand)
