The same thing happened to me on the way home from work in my disco, took the AA 3 trucks and 5 hours to get me the remaining 35 miles home.
1st truck took 40minutes getting there (from a depot 5miles away), and wasn´t even a AA truck, it was a clapped old thing from Egerton's. The PTO wouldn´t work, so he had to ring his mate.
2nd Truck arrived, another clapped out one from Egerton's with no seat belts! After setting off, the driver informs me he can only take me to place of safety and drops me at service station 5miles up the motorway.
3rd Truck (proper one from the AA) arrives 2 hrs later!
