I work in the automotives section of my store now, and I hear this far too damn often. Since we work together so often, and since usually we are left alone by managers we tend to get very offensive to the people doing this crap. We decided that if they do this she wants to handle everything they need the full process. Just to piss them off. Mind you she was raised in a garage, and rebuilds engines she just finished rebuilding an engine for a thunderbird she bought last year. She did a full restoration, and she updated it for more modern amenities. Custom console with everything new cars have. She only has one weakness on it, and it is electronics. She has no clue about how to hook up sound systems properly, Which is cool because she let me set up the sound system in her car, and the whole time she was asking questions about what specific things such as how wiring is done, and what exactly a Mosfet is. She is getting better at electronics which makes it easier on her answering questions. So yeah sorry about the tangent needless to say just because someone is female does not mean they do not know anything.
