Spilt Liquid !!

Driving from the south coast to an address in south London , I happened to have the misfortune of following a road contractors open backed truck which had open drum containers which I later learnt to my cost contained a bitumen emulsion. Whilst noticing a dirty drizzle occuring on my windscreen I had no idea whatsoever that it was emanating from these drums. I thought at the time that it was traffic film coming up from the road surface. Reaching London I navigated to the address to undertake a survey which was on the second floor overlooking the street. After a period I glanced out of the window and to my great surprise the truck I was following was parked in front of my car with its two operatives with cloths washing my car with a solution to remove the bitumen which covered the front of the car. They just happened to be contracted to fill a hole next to where I was parked and recognised that I had been following them for several miles on the main road . Upon seeing my splattered car they put two and two together, checked the open drums on their truck and realised with a concience that the were responsible for splattering my car and set about cleaning. I cannot believe how apologetic they were!
