[Jerome Betts]

I think I'm with Roger. People are over-analysing spoken communication, which has a lot of redundancy. (Gives the bran time to catch up with extra processing time.) Things that look inelegant or redundant in cold print may have a function when heard over a PA system. Something formulaic with a couple of words which more or less mean the same may give you a chance to switch on and get the message even if you missed the beginning of it.
