Milan early 1980,s the flights to Rome had been cancelled , I was bound for London with BA. A riot erupts a lot of Italian men storm onto apron and squat around a DC9 which apparently they wanted to fly them to Rome. Much negotiation and arm waving but with no way forward . Eventually Airport Fire Dept roll up and literally hosed the passengers down and away from the A/C. There looked to be quite a lot of expensive suits and brief cases damaged and some dignity.
Walking out to a flight out of Tunis from temporary terminal in cargo area with Dan Air on a Comet in 1971 and LH 727 already closed up and taxing followed a follow me jeep and taxied through the line of passengers. Nobody hurt but wing was very close and felt jet blast as they made their turn of the apron and onto taxiway.
I have mentioned this before but passengers at Lagos being made to run around a 737 on an internal service as flight over booked in 1980,s, winners got a seat and to fly.
Being served Chivas Regal and Coke on BCAL by friendly CC when I was only 13 heading back to school as pre dinner drink

There are more but will have to get back to you.
Cheers
