I ride a commuter bus to and from Redmond,WA and Seattle, and on a daily basis I hear multiple cellphone conversations. No matter what language they are in, they piss me off. I plug my ears up with nice plug-style earphones, listen to music, and still hear the chattering.
Message to all on the 545: STFU and wait until you are off the bus to chatter constantly. It's got less to do with language in my case, but you get the picture.
