get angry and start calling me names if I drive by you as you're trying to flag me. Odds are very good that I would just loooove to pick you up but once I accept a "job" for the company I cannot - at the risk of my job - stop anywhere along the way. I'm sorry.
DO however, feel free to get very angry and call me every name in the book if I happen to hear you calling me those names, pull over, wait until you catch up with me, ask you "I'm sorry, was that 'fucking bitch' you called me or 'stupid fucking bitch'?" and then drive off when you answer.
