If that homeowner is that scared of the his lawn guy, I would get a new one. Your lawn professional should be someone you can partner with and talk with not hide from.
That said, I know the LCO's point of view as well. They get tired of the type of customers that bellyache them and nit pick them, not letting them do their job. So they assume all customers will be this way, when in fact 1 out of 20 are like that. Then they treat them all the same way too, but the other 19 should be treated much better.
