....Is this sort of toll station for restrooms common in the UK?...

I remember learning about this when I asked about the term, "I need to spend a penny". British sitcoms are a great way to learn the intricacies, & expand one's knowledge of the Queen's language.

I remember there also used to be a seaside postcard with the picture of a man in Highland attire walkimg out of the ladies with two black eyes and head spinning as he'd picked thecwrong toilet & got a belting for it!!!

Don't remember spotting that sign last time I was in waverley station though!!
