By my place place of work is a small row of grotty shops, you know the sort of thing - a bookies, a greasy spoon, a funeral director, a corner shop, a chemist etc. In the middle of the shops is a door to a flat that I'm told is a rub-a-dub shop. How people know this I've no idea! Anyway the outer door is left open during 'working hours' and immediately behind it is another door with a bell and security camera. I've searched the local papers for possible ads but I can find no reference to the place. If this is a knocking shop where are the girls advertising and would it be good manners to ring the bell and ask if this is the local whore house?
