Hey thats great! I was thinking FSDT could do something creative too with approaching the marshaller at night with the taxi light still on. Make him turn around or with his hand before his eyes, waving with the other hand to turn lights off
(edit) they could make the characters more human. A real cart loader/unloader wouldn't stand waiting al the time, he would go sit on the rear end of the conveyor truck smoking a cigarette. Same for all other vehicle drivers they wouldn't sit straight up all the time but lean on the stearing wheel when parked.
