Once went to a remote country area knocked and knocked got no answer just as I turned a giant dulux dog appeared and jumped up had me pinned to the front door got it of and went to get back into the van to write a call card when I opened the door brute jumped in and sat in the drivers seat I pulled pushed and thumped him but he wouldn't move eventually a farmer came along on his tractor saw me and came to investigate looked at me and laughed ach he's a friendly big lad and loves the car he ended up tying a rope on the brute and pull him out with the tractor a delivery that should have took 1 hour to complete lasts almost 3 hours
