I am not the only person who has had trouble with the sexist bike snob bike shop. Woman from bike maint class had similar experience. She went in and asked for a new inner tube, correctly describing exactly what she needed, Bike Shop Bloke says "have you got your bike with you, I'll just go and check that's the right one". That's two of us never shopping there again. Lots more than two, when you count up all the people we've told about them. Hah.
