I guess day of week and point in quarter makes a big difference - both above were weekdays and not near quarters end. Day we picked up, I heard 300 cars that day, which by schoolboy maths equates to a car about every 2 minutes.
I was there one day in service centre in November having first set of problems fixed (still waiting for next lot 4+ months later) and it was a completely different story to ours.
The irony of ours was that we had already been there 6 hours as they had lost our car - they gave us a different car in the end. They then accused me of time wasting by wanting to check the jack points of the car, a 2 minute job. Some people did seem to get a better handover - I guess it depended on who was in charge of that side of the warehouse - the warehouse seemed to be split 50/50.
