Sorry to say, Rich, that was not the response I expected.
AFAIC, there is no gray area here. I have argued (yes, many have disagreed with me) the same for years here.
A little background...
I have seen more deals than you can imagine ruined because someone lost trust. As simple as that. The salesman fibbing to his wife on the phone in front of the customer. The contractor paying the 3rd party vendor a little extra to get his customer's deal. I even saw someone lose a million dollar deal because he took his customer for a ride in his leased car with the speedometer disconnected.
And the reasoning was always the same: "If he could do this little thing to someone else, what will he do with my big deal?"
It's not a matter of what is effective. It's a matter of what's right and wrong. For many people (me included, of course), there is no gray area.
I realize that jaywalking != murder, but deception in business tactics is always a big deal. When one has little more than your reputation to judge, all data that affects that reputation is fair game.
I was disappointed with the original post. Calling deception "a little melodramatic" and citing a pg naughtiness quote as an excuse leaves me more disappointed than ever.
