I communicate with a great many hospital staff members on a daily basis. Sometimes it is very difficult for me to understand what some hospital employees are saying. Some people have very very thick accents. Even though I consider myself to be a moderate Libertarian, sometimes I think that there should be a law - a standard pronunciation exam given to US citizens. If you can't speak clearly and properly enough for the "average" person to understand, go back to school or back to your "native" land until you speak English more fluently and clearly. Once in a while, after a busy day at work, I really feel this way.
