As a woman, I have personally experienced salespeople trying to sell me unnecessary products or services because they think I am naive.
This has mainly happened to me at the car dealership! I have noticed that when my husband has been with me, the salespeople do not have the same conversations with me as they do when I am there alone.
It is unfortunate that people try to take advantage of others to make more money, however that is how the world works. This recently happened to a friend of mine. Instead of this happening at a car dealership, this happened in her own house with an Heating and A/C supplier, but my friend purchased her first lake house ever, so there was a learning curve when it came to services and products she needed. Her central air conditioning system started giving her troubles the first warm season that she lived in her house. Her thermostat would learn temperatures, however hot air was blowing out of the vents instead of cool air. She did some research and found a local Heating and A/C supplier that seemed to be within her budget. The reviews were not as high as other local Heating and A/C companies, but she had to go with what she could afford at the time. When the Heating and A/C worker came out to repair the issue, he tried to convince her to buy hundreds of dollars of services that she actually did not need. Her gut was telling her that something was off, so she called her guy. Her guy friend has a good knowledge of heating and cooling, and he instantly realized that she was being taken advantage of by her local Heating and A/C supplier.
