Air Crew make a mistake, they are completely immune to any discipline
Cargo Clown is an appropriate name. You're not one of those 'us and them' types are you? You know the ones, when the pilot says ' g'day mate, hows ya day goin?' and they grunt and look like a bulldog chewing a wasp before walking away.
You might have picked up a few whiffs of diesel exhaust I reckon, maybe try standing upwind of the tug.
