When I am in the Admirals club next to someone who decides that they want to have a FaceTime or conference call right next to me, I just call up one of my buddies and have a really loud conversation right next to them. Sometimes I'll text my buddy and tell him or her what the situation is and ask if they'll just talk to me for about 5 minutes about blithering nonsense, and make sure that I talk just as loud as the person next to me. I love the quiet areas in some of the lounges, but even then some people still use their phone or have a FaceTime in there. Of course there's nobody enforcing any rules.
