You will find this to be the reaction almost anywhere and everywhere you frequent (especially when you request "feminine" brows). Also, when you are paying someone, they generally will be accepting (waitresses, store clerks, etc.). In male or female mode, I am completely open and up front about why I am buying whatever it is. I cannot tell you the number of times I have shopped for and/or purchased lingerie with a few days growth. There always has been and always will be a-holes in life, but most people are truly special and accepting. Now get out there and do it again!
