ran outa room.

Guys there are two sides to the story. Save your judgement on the guy the OP is taking about. The OP didn't tell us what he said in this 30 min convo. The guy had pretty much every right to do what he did. To the OP i suggest you think back to the convo and paraphrase what was said.

Getting told no isn't rude. What is rude is bugging someone for 30 min about an item he got, and you would very much want it. I can see him being rude is saying yess right off the bat then logging, but it took him 30 min to say yes. I think there is more to this then OP was saying, so again please hold judgement calls on the guy till we know more.
