I especially love it when they step away from their own travelling party, so that other, unrelated passengers in a different part of the lounge get the pleasure of having this very-important-person gracing them with their presence, pacing around in those other, unrelated passengers' part of the lounge, disturbing those other, unrelated passengers' peace in the process. When they step away from their own travelling party so as not to disturb their companions, this of course gives them license to speak even more loudly than is necessary.

Add bonus marks for having their correspondent on speaker, too.
