Surely They Didn't Mean That!!!

Many years ago I was working in Scotland and stopped in the village of Carnwath to get some cash from the bank there. I got the money and turned to go back to my car and saw something across the road that I thought must me a mistake. It wasn't , in the window of the local Post Office cum shop , bold as you like was this:

ARE YOU A TWAT

 After some research a mate of mine found a web site that confirmed that here : "TWATS (Tarbrax Woolfords Auchengray Theatrical Society) use the hall for their production of an annual pantomime." 

While I've got no problem with innocent mistakes and the like , you would think that someone would have noticed the acronym was in fact a very naughty word!!
