It's alright though, it's all stuff you can check yourself...
No, he has a warranty to worry about.
But blowing £170 on oil and a pair of filters along with an anti idiot check on a car that is well out of warranty is quite simply being ripped off.
Last time I took my car to a Ford dealer it was due to a failed rubber bush on a 3 month old control arm which I insisted they cover the labour on as it's in the terms of the parts warranty regardless of who fits it. They then tried to insist I had one of the water hoses changed that exits the water pump as it was slightly perishing, they wanted to remove the front bank cam cover, catalytic converter & waterpump to get access.
This involved replacing the front cam cover gasket at £48 and replacing the entire pipe assembly at £180 with labour on top.
I told them where to stick it, I changed it that afternoon as it's an easy fix for less than the cost of a takeaway, a £12 rubber hose that's about 6" long from the local motor factors, I just accessed it from underneath by sticking my arm up the back of the front bumper, it was held in place by a pair of jubilee clips, 10 minutes under the car and it was done, £300+ saved, only tools needed were a 6mm socket and a philips screwdriver. That said, it probably had another half decade in it before it was an issue.
Most of the stuff on these multipoint checks is just the basics like are your tyres bald, are your fluids low, do all your bulbs all work, are your pads & discs ok, are your belts shot, are you capable of dressing yourself type stuff.
