Never had any problems that I can think of, apart from once with a car driver.
Unfortunately unless EVERYONE boycotted the ferry (and that's not going to happen) then they have us by the S&Cs.
All you can do is voice your disapproval and then calm down and preserve your blood pressure.
Maybe if everyone witheld their payment past the end of March then it might possibly have some effect, but again that's not going to happen is it?
