In Medieval times when you wanted a leak you just popped outside and did your business on the cobblestones or in the gutter and it would (hopefully) run away with all the other medieval fluids and detritus.

No such things in those long-distant days as ‘facilities’, ‘the gents’, ‘the ladies’, nappy-changing cubicles or disabled loos with emergency cords.

Haven’t we come a long way?
