Don't know about the guys - but ladies don't be surprised when you go into a WC and stall doors are open while "business" is being conducted. If you're not comfortable with that yet, don't be afraid to wait for one that has a door or go all the way to the end of the bathroom (by a fan is best). But most importantly . . . DO NOT EXPECT THERE TO BE TOILET PAPER! Thankfully I never go anywhere without tissues. Carry a travel pack of tissues (and hand sanitizer) with you. You'll never regret it!
