The issue for me is expecting mate to drive about 10 miles with just a cambelt, with no PAS, hoping it won't overheat, and battery will last.
No way that should happen, and second bloke that came out said he was embarrassed by it.

Coils are common problem I grant you, doesn't take too much brainpower to swap a couple round, and see if the same pot is missing a spark, like I did.

Broken down in lorries a couple times with terminal problems, policy to send a man and van first - if they send a wrecker when it could have been fixed, someone's gonna get shitty with paying for needless towing.
Suppose most use same policy.
