Be glad he rejected them, you are OVERPAYING.
But yes, some owners think their guys are better then they are, but it's more a case of greed. They try to take you for a sucker. If they intially offer me a bad trade I counter and explain why I did, but if I send them a fair trade and they piss and moan or counter with some BS I really get pissed, because they are insulting my intelligience.
The guy is not someone you want to trade with, just let it go.
