Hey, Zack, don't feel bad. That stuff happens to a lot of people, not just kids. I used to go to Radio Shack until I noticed that the only customers that got waited on were young men.
As a woman, I have to grit my teeth and hold on to my wallat when I go into an auto repair shop.
And you think its unnerving when you get treated like that at the store, what if you actually paid someone to come to own house to work for you, and then they ignore what you are telling them needs to be done, just because you're a woman....that's life. Take it with a grain of salt.
