From reading some of the above responses I now know that asking WYBP is not an insult, but a strategy for negotiating. It's kinda' like walking into a club and approaching a woman with the line "Let's screw". You always could get lucky, but it shows you to be a pretty lame pickup artist and/or equally amateurish negotiator. Any negotiating strategy or ploy has to be judged by its effectiveness. If it works for you..., but I'm going to ignore you.
Thank you very much.
