Bizarre experiences - who invited you in here?

In any city there are never enough public washrooms.
On this particular day I and about a dozen other men were in the toilet just outside the Taganskaya Metro station in Moscow, all seemingly having found the place about half an hour later than we'd wished, standing at the urinals relieving ourselves.
Was that a pair of high heels & a woman's voice I heard coming down the steps?
As I tuned to look, there was a very well dressed woman, probably in her late thirties, holding the hand of  a 5 or 6 year old boy. She took no notice of us & proceeded to march him up to the urinals where she assisted him in undoing his fly. And when he was finished, she marched him out.
Needless to say, everyone had backed away from the urinals and stood in disbelief at what they were watching. Like many public places in Moscow, not a word was spoken....but the looks we exchanged afterwards clearly said "what the fuck was that about?"
