Some of those PA's on TV are so disgusting. Mostly they are an attempt to stop someone from smoking. I don't believe it even works but it just bothers me to hear someone sucking out dental appliances with exaggeratedly loud noise from their mouth. I have to turn away and try not to listen. Also really hard to take is those with throat or facial cancer. Does anyone think this kind of PA really is something that prevents this type of sad outcomes? If it really does then I might bear with them. But I just wonder. It's horrific to have to watch.
