so like, where i work there is a wardrobe and showers for those who cycle into work, so that they can all freshen up before heading into the office and don't have to sit through the day all sweaty and gross.

i've been cycling lately and luckily it's not a very long trip for me, so i've just brought like a clean t-shirt or whatever to put on when i get in. but now it's getting hotter and i'm thinking it would be sweet as to use those showers before heading into the freezing cold airconditioning and whatnot, but i'm worried about the shower etiquette (hence the title). you see there is nothing separating the three showers, no curtains or anything, so at any time one of my dozens of female co-workers could come in. and this makes me uncomfortable and i don't know what to do. ADVICE?

thanks dis xxxxx
