I was standing by them talking to a guy tonight using /say. For some reason when I said something all 3 bankers turned around and looked at me. Once he left I was standing there trying to figure out what I had said that made them turn and found out it was "Grouping". I tried it several times and every time I said it with none of them targeted they all spun to look at me. I tried targeting them and hailing them but couldn't get any other response no matter what I asked them then.
Just thought it was strange.
