While I hate to say slanderous things about anyone, sometimes things must be said.
The first time I met this person was in a PT during my 50's. They were levelling their RDM, and they were wearing, yes, full RSE. Now, I understand that people are poor, but that is no excuse for not being able to fulfill the simple duties required of your job. After being told by the party that she would be kicked if she did not start casting refresh on people, she shouted at all of us and left. (Note: This was after about an hour of simple and polite requests sent in tell asking for a refresh).
Last night, this person went on one of the KS BCNM30 runs with my group. Since they were a lv74 BLM, I dropped PT and let them go with the other 3 (partly so they wouldn't have to split 5 ways, which would be kind of unnecessary, and partly because I didn't trust them). Well, damascene cloth dropped on the orb and this is the conversation I just had with Muffins: (This is from AIM, and I changed the screennames heh)
Muffins: our friend, xiaoquin, is stiffing us on the cloth that dropped
Muffins: she felt she deserved a cut from the other runs we did, ya know, the runs she wasn't even a part of
Muffins: she said we were "rich enough"
Pax: Told you I didn't want to help her
Pax: That's why she was already on my blist
So yeah, I would definately watch out for Xioaquin. While I wasn't burned, the other BLMs do not deserve this. For confirmation of this story, you could ask Sirdan, Leomagnus, or Muffins (the other BLMs that participated).
