I must say that I agree with you a client has every right to sit on your shoulder while you are working, after all its their boiler!!
there could be a myriad of reasons why this chap had trouble fault finding your boiler
he could have been out and about for ages, I for one know the feeling of being cream crackered and trying to get your head around the tenth different boiler you have seen that day, we really should have tachographs in our van with the hours we do. It really goes with the territory and you should get used to it pretty quickly. Also I never under play the part a client can have in diagnosis if you just listern to them when you arrive they can normally, usually unintentionally, point you in the right direction.
he may not have been that familiar with your boiler, must say this used to happen to me a lot when I first got started (on this point has the ACS cen1 changed as when i done it three years ago there was no fault find, other than gas safety issues included if they have change it GOOD about time) but I used to be honest with the client straight away and then book up a course with the maker ASAP.
I really respected then way he put his money where his mouth was by saying if he was wrong it would not cost you anymore, I feel this is a very professional approach and he should be cheered for it.
i get the feeling from reading your post that this is the most likely reason and he should have said so to you.
Please remember that "rip off artists" are very few and far between and most installers (for want of a better word) believe strongly in personal professional development. It has already been said the nearly ALL manufactures offer very comprehensive training on their products, personally I attended at least three manufactures courses a year to refresh and update, and I reckon most installers do the same, seeing as I regularly meet up with the same bods from time to time.
