I was told off in front of everyone in the middle of the KH for answering up. The previous weekend my restrictions were lifted (following a JC a few months earlier) and I was encouraged to answer in the Service Meeting, which I did. after the meeting an elder came up to me and angrily said "why did you answer up when you're not allowed to?" I wanted to die on the spot.
Less serious but maybe more daft matters I was counselled on over the years:
As a small child, listening to Abba songs ("they are immoral")
Again when I was a kid, wearing a badge (I think it had come free with fizzy drink or something)
Later on, wearing a beard (wasn't formally counselled but just got a few barbed comments hehe. Ironically they made me an MS even though I didn't shave it off)
