I agree with Molly, I too am considered one of the guys, never faced any trouble since I AM the best of them technically, and no I never faced any problem convincing anyone that I am competent, and never had to put extra efforts into it, because I get my clients through referrals who describe me pretty well… but I guess there is no problem in pre-assuming that woman are not as good, because it does happen that more than 90% of a certain vocation is inhabited by men, and the case is correct on males as well… I do not wish to have a make baby sitter, I alwasy preassume he doesnt fit, neither a cook, or a barber, or a decoration engineer (woman are always better;) ), so you see the point, it goes both ways, i think its only human, and we shouldnt be sensitive to the issue, u just need to play a little harded the first few steps, but afterwards may the best win it all!
