Both examples of good contributions from a junior AR, and exactly what I would want, but not that relevant to what we're discussing.
Obviously both AR's are there to help you get decisions right - but that's not the same as inserting themselves into petty admin that you should be capable of handling on your own. And maybe you want to go out of your way to confirm with the senior AR, but any junior AR insisting on shouting at me or flagging me over to know who was cautioned will quickly be told to shut up and leave me alone to concentrate on more important things.
Remember that we are on a thread where the OP was junior AR, and
@Anubis has multiple times referenced having
three books match. I don't ask my junior AR to take notes at all (eyes and ears), so I'd be very unimpressed by them calling me over for this reason: both becasue they ignored my instructions, but double-so that they then interrupted me in order to do so.
