Totally agree that change will only come through action from us. There are, I am sure, some owners who don't care - but I suspect they are the minority. We are paid, IMO, to run the aircraft as economically as possible. We have a standard handling quote form now that is sent to FBO's, if possible at least two at destination, which list everything we would need. That way we can at least pick the best value and have written evidence of costs that can and can not be charged.
Many FBO's now are seriously beyond belief - it's not my money I am spending, though it feels personal that some take such liberty and take the attitude that it's your problem if you complain.
