Cars Parked in the Way

On of the problems we face from time to time are cars that have been parked that are blocking the road. The driver has just nipped out for a moment to the Cash machine, Take away, Doctors, Pub and have left room for all the motor bikes in the bay to get past but not an 8 foot 3 in wide bus. The usual procedure here is to sound the horn and then get a newspaper out and have a read. After a few minutes the driver will then get on the radio and inform control. One such incident yesterday went as follows:-

Driver, "Papa 12 to Yellow control."
Yellow control, "Go" (1)
Driver,"I am stuck in Midvale Road. There's a parked car in the way."
Yellow control, "Have you sounded the horn." (2)
Slight pause followed by the sound of the horn being blown twice coming over the radio.
Driver, very dryly, "That's an affirmative." (3)

Foot notes
(1) We don't go in for correct radio procedure, none of that over and out stuff here.
(2) It is of course illegal to blow the horn on a stationary vehicle unless to avoid an accident.
(3) 'Affirmative'; bus driver slang for Yes.
