Well lets see:
They weren't his staff, they were his companies subcontractors staff.
He isn't a particularly high profile character so how would anybody know who he was from Adam?
Someone ranting and raving in an airport queue wouldn't normally make it to the Daily mail even if the police were called.
He knew exactly who to speak to if he had a complaint, because he approves the contracts.
Now he is a folk hero?
Now he has some publicity?
If one of his own staff, had actually behaved in this manner, he would have had them out in a heartbeat.
Yes clearly a spontaneous outburst, not!
