Acknowledging Subs

As a frequent sub, and a band leader who frequently needs subs, I often reflect on the importance of acknowledging the work that these guests do for the ensemble. Sure, you may get section mates that lean over and say "nice work" but unless the leader of the group introduces the new player and thanks them afterwards, the guest may leave with a "bad taste" in his/her mouth. This is also true for situations when the sub knows the leader of the band. Never take the time investment of the "sub" for granted, as that player may be not be as willing to come in the next time you call. Now, to be clear, I have seen this error from both sides. I have noticed old friends/band leaders not acknowledge my presence the entire night and I have kicked myself after my own rehearsal for not introducing the guest player and for not thanking him/her afterwards. It is something that we should all keep in mind.
