A good tip, and a reason why I always bring along packages of pre-moistened towlettes while on vacation with me everywhere. (U.S. bars, restaurants, and other "public" toilets do not always have a way to clean hands, either.) Yeah, I'm compulsive, and my boyfriend laughs NOW. But I think he'll appreciate it when we arrive in Spain and he finds a package in his backpack while in the restroom!
Thanks!
