During a crosswind wing-down landing there's nothing worse than starting to put the rudder in only to find the pedal is much stiffer to push than normal. For a split second you wonder if you have a control problem then quickly realize that it's because the guy sitting next to you has his size 9's firmly planted on them. As there is a lot happening during the wing-down flare there is no time to say 'get your feet off the pedals' - you just have to deal with it.
My feet stay on the floor and my hands off the controls when someone else is flying - as do 'most' that I fly with .
