Two thoughts/replies.
Many years ago, arrived in O'Hare and experienced very heavy braking. Knowing O'Hare uses things like intersecting runways I just assumed it was normal until the flight deck apologised and explained that the plane in front of us had been a far eastern 747 and he thought we might like to get to the terminal first.
The other incident was a 737 into Belfast when I had the privelege of being in the cockpit jumpt seat. On finals the first officer turned and said "we're now going to show you a short landing in a 737". OK, I thought. We dropped the mains on the runway as soon as we could followed by reverse thrust, lift dumpers, heavy braking. Turned off the runway and taxied to the terminal. After they had turned everything off I asked why. Well, came the response. There are three exits one at each end and one in the middle. If had had to go to the end we would have had a long taxi back to the terminal and we'd have been late.
