Most ppl think and act as though a surveyor is there to make their life difficult.
I have been dealing with the CAA for 20 years I always treat them politely and with respect, I take the attitude that they are there to help me.
On the odd occasion that they have noticed something I have missed, I was honest that it had slipped through my inspection and ask if they have any recommendation as to what I need to do to meet their requirements.
They have always been helpful and never refused a CofA or felt a need for a return visit.
On the other hand I have seen ppl argue with them, shout at them and one guy even threatened to sue. It never works.
