Ugh, that reminds me, when I was helping train the remodel team, I was working SFS on a non-training day and the service desk TM walkied me saying that there was a guest who wanted to see me. Wouldn't tell them what they wanted, and I finally gave up and went up. It was the mother of one of the remodel TMs, and she had a question about something HR-related, and apparently she looked at his schedule and saw me under "trainer".
Told her that I didn't think I could talk to her about anything like that since her son was the TM and she wasn't, and as it turned out, she had already tried to pester HR and HR had told her no.
