The main phenomena here is that drinks have jumped off of the bar into peoples laps. Raps have been heard late at night when the bar is shut and nobody is there and even the smashing of glasses has been witnessed without glasses actually being smashed.
Nobody knows who or what it is or why. I do know at one time it was used as a prostitute den in years gone by for people getting off of trains and wanting a bit of a thrill before going on to what they have got to do.
