I was thinking the same thing. They need to enforce this in libraries too. When was it okay to all of a sudden hold a loud cellphone conversation in the elevator,libary,or a classroom? Cellphone etiquette has taken a nose dive.
Btw,why are people so damn loud. Cellphone technology surely has improved vastly enough where the quietest whisper can be heard with great clarity but people still insist that they need to broadcast their lives to unassuming people.
