Ahh yes, the good ol' "how you dress", "how you carry yourself", "your personal hygiene", "how you talk" or one of the other hundred responses I get from people immediately when I talk about the unfair treatment I've seen in my life. All I can say is no it has nothing to do with how I dress, because half of those "random checks" were during my business trips when I worked for a major consulting firm. So I doubt my suit and tie had anything to do with it.
