That's the point, no one needs to be rude, I say what we offer and if they're interested, if not, it's a thanks for your time an no need to hassle them.
If you're a decision maker, you get calls, I get calls, an I'm always polite because they're doing a job an they may have something of interest to me.
If your a little turd who knows nothing and are still rude, you're a jerk
