He works as a PR/Marketing Mgr always out with clients. International clients are the worst, your like their bitch until they get on their plane, on call 24/7.

He had stupid calls about hotel not providing toothpaste or slippers. Or they got lost and need a pick up but don't know where they are... etc

Also its the company's phone so naturally he doesn't want the boss to find out that something illegal is done.
