I own a car repair garage and i can always tell when a dick has decended upon us, they will either drive into our garage univited rather than park up and walk in, or they will pop their bonnet believing they are the next job and we will drop whatever we are doing to serve them next, or sit outside pipping their horn wanting us to run out to tend to their instant demands or present us with the parts they have bought themselves thinking this saves them money or or.... im about to have a meltdown just thinking about them, they are everywhere, they are always behind me in traffic and somehow infront of me as well....and they are overtaking me, im surrounded arghhhh. :)
