My dad was on the same flight. It landed and some guy sitting in the back made a run for it down the aisle as soon as they came to a stop. Fred stepped out into the aisle and blocked it--the guy ran right into him. According to my dad, Fred had a stupid grin on his face and asked "just where do you think you're going?". The guy did the walk of shame back to his seat and got in line.

I guess Fred had to hold the guy accountable, but in this case, I agree.
