I hate having my cars serviced by a dealer. Charging for things like the afore-mentioned pollen filter, and my particular bugbear, screenwash (I always tell the service reception monkey that I won't be paying for screenwash, so don't bother putting it on the invoice), and then, unless I make it clear that they are not to go anywhere near my paintwork with their filthy, grit-encrusted cloths, "cleaning" the car.
Something which irritates me intensely is the feeling that once my car is on the dealer's premises, they seem to forget that it's my property, and they don't have any duty of care towards it.
A good, honest, diligent independent is worth finding.
