Airline Club Etiquette: Cell Phone Use

I was in the United Club at PHX today and an older man was talking very loudly into his cell phone while seated in the general seating area.  It was so loud, and he was being rude to a United call center rep too, that I asked him to keep it down.  He didn't.  I later told him his 2.5 hour delay last week due to an equipment change was an operations decision and that was it.  At one point he said "hijacked my plane."  Don't say that in an airport!

The lesson today is to talk softly or excuse yourself to an empty area and to watch what you say.  Everyone was uncomfortable because of one person too wrapped up in his moot problems to care about those around him.
