So? If I'm sitting that means I don't want to stand. And I sure as shit wont allow a bus driver to discriminate against me. He can put any sign he wants, I'm still going to sit where I want. Especially when you consider I pay full price to ride there and those old people and cripples pay a reduced fare. As far as I'm concerned, I have more right to sit there than they do.
Sorry for hijacking the thread
Now I think I worked myself up in to taking back the advice I gave in my first response.
Tomorrow, if you see that broad on your machine, pick her up and move her. She needs to learn respect. You probably paid more for your membership than she did. So not only were you there first, you should have priority regardless.
