cell phone etiquette revisited

You've all heard the polite, and someimes not so polite requests to turn off your phone during a theater performance or movie or concert, and it seems logical to me that I should turn off my phone during a church service or any kind of meeting. You would think so, right?  This evening the situation came up again with a slightly different twist. Granted, I was at a rather casual church meeting but I was trying to pay attention to the information being shared by our guest speaker. About 10 minutes into his presentation someone's phone went off with a very melodious tune. After a lot of blank looks around the table the speaker realized that it was his phone, took it out and layed it on the table. After three more interuptions by the ringing phone, he looked at it with a bemused expression and said "I guess I could turn it off."  Really? What a concept.
