In my experience changing the flying programme at 22.00 then at 01.00, 02.00, 03.00 and then a crew arriving at the FBO without notice at 0330 with an aircraft stuck at the back of the stand behind the other 8 aircraft that were supposed to go first is always a good way to run an operation
The sympathy for the crew is there but the good will for the operator left a week after they moved to the FBO.
