I usually give notification based on how chatty my group is. If no ones talking, you'll get a 'got to go soon guys', 3 pulls later, i'm out.

If everyone is having a real conversation I'll usually bring it up way beforehand -- one of the first questions i ask is 'how long does everyone have today?'

Part of it, if you're the group leader, is being proactive. Rep-finding is pretty rare, and I've only found it to be super common in higher level groups. Lower level shindigs usually don't get nearly as much consideration, as disco is a much harder camp to keep than MR in unrest.
