If people specifically wanted to
know what the guy looked like, then his colour of skin, along with other
descriptors like his height/build, would be useful.


Height: 6ft
Weight; 14 stone
Fitness: moderately over weight
Eye sight: poor, glasses
Hearing: poor
Language: working class poorly educated
Demeanour: confrontational, argumentative, unstable, unhelpful to the
travelling public, possbily racist against white people, possibly prejudiced
against suit wearing educated management grade travellers.
Smell: typically unsavoury of a privatised "public" sector worker.


Any other details you require?


I think "black man in blue hat" was actually quite generous.

"Left wing racist working class smelly ill-educated jobsworth" would be
equally accurate.
