Same here. Every time one of my driving staff has been in the captain's chair I have to go through all the switches and buttons to turn off the turn signal, fans, transmission retarder, and reposition the seat... Any number of those get toggled to random positions in real life whenever the bus is driven on some make-believe adventure. I have to admit, some of the switches, levers, and knobs really are kind of fun to operate.
I guess it would be good to bleed off the air from the brake system when I park it just to be sure they can't release the parking brake. Of course, they do enjoy the sound the first few times they pump the service brake!
