I do the negotiating also. We needed a new car so I was shopping around this past summer, and it took about 15 minutes before anyone even greeted me. They all assume that I am with some man and that "he" is off talking to the sales person. This has happened to me at the store when I went shopping for a dishwasher also. Anyway, the car dealer that finally helps me only asked me what my favorite color was and then told me that I could not afford the more expensive car. He had no clue what my financial situation was. Even with my husband around, I will ask a question and the sales person will turn to my husband and answer. I am a totally normal looking person. I speak perfect English with no accent, and ask intelligent questions. Maybe it is the area that I live in that has an abundance of sexist men. Obviously not all men are like that, but even my husband is shocked by how so many men treat woman in our area.
