Just a guess, but he was probably pissed you were transferring a gun that he could have made more money on selling you himself.
If thats his attitude he should increase the price of his transfers and stop being a dick.
I always ask my local guy if he can get me something before I ask him to transfer anything new thats readily available.
I figure saving a few bucks isnt worth it if the guys isnt still in busness to transfer my oddball Gunbroker finds.
Shouldn't matter, they should just increase the price or not do the transfer then. It's not too much to ask them to be professional about it.
