"He that is without sin among you, let him first cast a stone.." 
"Devil's advocate": Was it at night? Maybe somebody started it all by taking a wrong turn. (There is talk of a "Hawker" cutting in front). Several times the freq. is "stepped on". Somebody calls for push back or taxi but are on a wrong freq. or not ready. The pilots are really trying to help, I think - getting the "picture" across - or back - to the controller.
"God's advocate": If this guy is getting in this kind of mess every day, yes, maybe he is in the wrong place?
