Lol first off i feel really bad that you went through and replaced his name with"caw". All that work to protect some troll.
Second like this guy seriously over reacted. I mean i think that if you over react that much it means something. Most likely he had no intent of trading with you, rather he was going to cheat you out of the coords or rip you off in some way. I mean any deal is not certain till the exchange. Ive had people back out of some deals before i mean it happen. That being said you were saying he would get the coords, so he just had to wait, what probably not even 24 hours. A very harsh response from said troll. Maybe instead of calling others a troll he should look in the mirror for the real troll.
