adversarial attitude to the customer
I'm not going to get into the proverbial peeing competition with you, but I can assure you at grass routes level there is definitely not an adversarial attitude to our customers, in fact, quite the opposite. Regularly, those doing the job go out of their way to make sure it gets done despite the ever increasing hurdles that are put in our way. If your operator is adversarial, then I suggest you change them, after all, you call the shots.
If the oil companies and their aviation experts can do it better and safer, know all the answers as HC says, then why aren't they? Because, it is easier to drive the price down amongst competing contractors. I would like an oil company pension and equivalent salary to the OIMs, so bring it on, I am ready to sign up.
Trickier one to answer without just being "adversarial" eh?
