Okay, you have your view, and I have mine.<quoted text>
As it turns out? I **am** in the business of selling things to people; I'm self employed.
The money from rude customers spends just as nicely as the money from the nicey-nice ones.
Sometimes, the rude ones are more honest.
But in the end? If a potential customer gets out of hand? I always have the option to tell them to have a nice day, walk away, and then ignore their telephone calls from henceforth.
I seldom have to do that; rudeness, I just ignore. Since I'm fixing AC's, many times their rudeness is due to being nearly overwhelmed by the heat, and I don't take it personally--even if it is said in a personal way.
But I would **never** ever deliberately cause someone harm or waste their time. That serves no one, and helps no cause.
I'd simply walk away, not looking back.
That is the best "revenge" anyhow-- living well, while a rude person will continue to be rude--and will most likely get rudeness back in return.
Evil always begats more evil-- never kindness.
I interpreted it differently when I heard it.
I tend to look for the good within what seems on the surface to be negative.
