When you fly charter, ferry or corporate in places like India and Middle East, Asia etc,
everyone needs three or four bars just to move around the airports and get things done.
In the U.S.A. you get just as much respect in a tidy business suit, or shirt and tie
(the FBO marching/marshalling girls are more likely turned on by the amount of fuel your 'iron' guzzles). Only pilot dress code thing gets up my nose is 250 hour CPLs driving Aztecs and Barons in the full four bar Captain regalia, as this really is not appropriate to the weight of the iron. Two bars maybe, unless you take that Aztec to India, of course.
