"So...quit using "cowboy" as a negative adjective, please!"

It means something different here in the UK (as we've never had cowboys in the US sense). Here cowboys mean fly-by-night workmen, bodgers (although that implies bodgers were clueless which is not true either), half-wits and people who don't do a proper job when working. Lazy, uncaring about the work, placing no value on skill or professional pride.

So don't take offence - none meant!
