I think some are missing the point here. It has been said that it is not worth your job. It isn't. But it's sooooooooo not worth your life either.
Livin, it's really great that your wife can handle herself, but stop and think for a second. Can your wife handle herself against a man when that man means to harm. I would never say that one of our male drivers would ever do such a thing. But what if it was me, on rte, I flirted with a male customer and thought it all innocent. What if that man didn't think it was all innocent. I could what if........................... all nite long. And I know your thinking, well that's a man against a women. Sweetheart, there have been plenty of women go after men with not so innocent of intentions. It can and does happen.
Mostly, we would probably never have an issue with a customer flirting with us or we flirting with a customer. But, what about that 1 in a million time? Is it really worth your job or (Lord forbid) your life? Would you want your wife in that position?
