Don't act like you just stumbled on a drug deal or a mafia contract killing; no one is going to fit you with cement shoes as a result of what you see in a unisex bathroom.

That being said, no one wants to be leered at while they are using the loo. We're aware that you probably aren't the kind of person who gets off on Peeping Tom action (we hope), but remember that most people don't even let their significant others know they use the bathroom at all until at least three months into their relationship. Do yourself a favor and keep your eye-line clear of anyone else's waistline.
