feel the need to take their clothes off in front of everyone in a changing room when cubicles with curtains are provided?! i don't understand it! i work in a clothes shop and we get quite a few people just stripping off in the middle of the fitting room when there are loads of free cubicles. why?!
maybe they feel comfortable and lack the normal british reserve, maybe they feel that no one will take any notice.. also to add some changing rooms are open plan, maybe those people are used to that type?
Are these blokes or wimmin? Male facilities at gyms and stuff rarely have cubicles, perhaps they are just used to it. Especially given the fact that you keep your pants on when you're changing in a shop (unless you're trying on pants althogh even then I might be tempted to do it in the superman stylee.....)
