I thought this was the High Road?!?
It is. The measured, polite responses you've received after you insulted most posters in this thread demonstrates that nicely.
It's like someone selling their BMW from the parking lot of a BMW dealership.
Depends on how it's done. If I set up shop in the BMW parking lot, hoping to score a buyer for my car, I would expect to be tolerated for a very short while by the dealership, until they understood my purpose. Then they would ask me to leave, as is their right. So I would drive off.
If, instead, I show up in the dealers parking lot thinking of trading-in my car, but begin to leave after deciding against it, and then another customer offers to buy it, that's different, IMHO.
Even in the first scenario, if I do find a buyer just as I'm driving off, I don't owe the dealer any money,
unless we've come to an agreement that I do. Doesn't change that it was an unethical--and rude--thing for me to do.
But in the second scenario, there's no problem with ethics; heck, there isn't even rudeness.
