I was riding back of a CRJ once and I swore that on landing the pilot had the wrong xwind correction in and we land all sideloaded and and you could feel him yawing back and forth trying to hold centerline after touchdown, when I was walking off there was a heated conversation going off in the flightdeck between the CA and FO, I popped in and said thanks for the ride and I saw the captain sometime later and I asked what they were fighting over and apparently the FO had the wrong xwind correction in and the CA said something and hes like "I know," so the captain just took the controls from him and fixed it real quick for him and the FO didnt like that very much and had so heated words for the CA on the ground even though the FO had the wrong correction in, apparently he only had 280 hours so that explained a lot...
