the basics are pretty obvious.....be very clean, sharp, "all there", sober, friendly, relaxed, calm and collected......
I also don't like cologne, antiperspirant, floral scents, etc.....please just be soaped up and rinsed off.....
if walking thru a hotel, public space, lobby, be discreet and low-key....no crazy clothes.....don't draw attention to yourself.....
talk slowly and just hang out like a good buddy.....
