I agree with everything that's already been stated. My biggest pet peeve is guys in the dealerships (like at the parts counter) who tak down to me. They condescend because we're female, and they assume we don't know what we're talking about.
The worst was when I went to get a replacement base assembly plate for my boyfriend's Helmet. I had called ahead, knew they had it, but couldn't find them on the wall with the helmet accessories when I got there, so I had to ask for help. When I told him what I was looking for (and I had to explain what it was, since based on the name, he had no idea), he asked, "What kind of helmet does he have?" I replied, "Who says it's for a him?" He stuttered a bit, paused and said, "Oh, I thought you said it was for your husband." I said, "No, I said no such thing." He got embarassed, found the part, and sheepishly started to walk away, when I added, "You really need to stop doing that." He asked, "What?" I said, "Assuming that if a woman is in here, she's buying something for her man. More and more women are taking up the sport, and with that attitude, you're going to lose business." He apologized, and I went on my merry way.
