Offer / counter-offer? Audiogon rules

All you guys are entitled to an opinion, but there ought to be a rule for the site that everyone knows in advance or it is not a fair trading platform.  This should not be a questionable area, but a known and published set of rules.  Consider a highway speed sign:  should it say drive at a safe speed or---should it have a fixed limit that everyone understands.

There isn't anything vague here. He received an offer, he declined. Case closed. Simple. What isn't simple is that he now wishes he had accepted the offer. 

What's "questionable"?  Common sense dictates that once the offer is declined it's off the table.  Making a counter-offer is declining the offer.  You're basically saying "No, I don't accept your offer, but will accept ________".  Do you really need a "rule" for that?

"Take it or leave it". "Opportunity knock's but once" "Strike while the iron is hot" "One in the hand is worth two in the bush"
