I was amused by this article from the BBC:

Paris metro: Pregnant Frenchwoman fined for walking wrong way

Of course, I immediately considered the cultural possibilities.  Young Frankenstein with the marvellous Marty Feldman….

Or better still, Monty Python…..

But the truth was far more jobsworth than that….

Social media has reacted with outrage after a pregnant Frenchwoman was fined €60 (£54; $74) for walking the wrong way at a Paris metro station.  The ticket was issued when she tried to shorten her journey by walking counter to a one-way system at Concorde. Paris metro operator RATP said the system was needed to control flow and prevent “incidents”…..

One Twitter user pointed out that the fine was more than for not having a ticket, adding “words fail me”.  Another suggested that instead of fining people for walking the wrong way, they should be fined for standing on the left of escalators.

However, if the unfortunately woman  comes to London before full term, this could be useful.  Even if it shows that you may have to travel for miles to find a suitable public convenience – probably at your inconvenience.
