Believe ATC when they tell you something. A few years ago I was landing at CSG with a 727-200 full with football player, fans, friends, and cheerleaders. I turned about a 3 mile final to follow a Baron on a mile final. The Baron was getting instruction and the flight instructor was handling the radios. The tower told him that they needed to land and turn off at X intersection traffic on short final. The Baron replied they would try but since they were cleared to land they technically had the whole runway to use. The tower again requested that they land and turn off at X intersection. The Baron replied that they would try but noted that the whole runway was theirs. They landed and missed the intersection, then they proceeded to do a 180 degree turn to taxi back to the intersection. At that point the controller go real mad, I was already spooling up my engines as I knew I was going to have to go around. When the Baron finished the 180 on the runway his windshield was full of a 727 all lights on and a lot of black smoke as I was spooling up for the go around. The Baron taxied off the runway through the ditch and to the nearest taxiway. We all laughed as the controller chewed out the instructor pilot, had they even continued to the end there would have been plenty of room, but no "the runway was all theirs-technically???"
