Amsterdam Airport
Bathrooms open to the public

At first, I thought my eyes were deceiving me.

Irrespective of gender, the sinks and mirrors in the mens and ladies sectors are open to public view. And the mens urinals, too; although in their case they are judiciously located so the man's back is to you. Toilets are individual closets as it were so there is privacy of a kind.

I think the cleanliness of the mens room is explained by this open to the public design. Perhaps, too, there's more rapid turnover in the ladies room for this reason.
