The thing is that it could have been any other number of ways. I mean it is possibly that the guy felt that he didn't owe you and it was his NM or whatever. Could also be that he figured that you left. You pointed him toward the bees, he didn't keep track of whether you stayed or left. NM spawns. Who takes the time to look around to see whether anyone else would iike to claim that NM?
I am not saying he would have done that, but had he been an NA you could have chatted him up and perhaps worked something out, who knows.
Point is, he may have shafted you on purpose, or he may not have, there is just no way to know for sure sure.
