Am I Alone?

Now, lots of people have heard me rant about gender specific single occupancy public washrooms, and my annoyance with them hasn't subsided. I am still uncomfortable and awkward standing in a hallway at the back of a restaurant waiting outside the men's washroom, while the women's door is wide open almost mocking me. I still think that if we allow ourselves to divide up our world along gender lines in the back hallways of restaurants, then we can expect no less a division in critical places.
But lately, my new confusion with single occupancy washrooms only applies to the men's version. It seems there is a trend towards putting a urinal into these types of washrooms, which I think confuses most of us. Do we lock the door or don't we? If we do, we feel ridiculously prudish and if we don't we risk a much more awkward situation as someone may choose to use the toilet. Can't say that I am a fan.
