Yes i had one quite locally,and im sure the owner who was a nice lady did "favours" of somekind for her customers,i think handjobs. I was once in there and a guy went in,he said something under his breath and she invited him round the back about 5 mins later he came out all smiles,and she was rubbing her hands with a wetwipe...i was always tempted to ask but too scared,but she did give me little hints.
