Question Author
Interesting and revealing, Spudqueen. I fell into the Hoover Vs Vacuum cleaner trap and assumed that they were the same thing - such is the power of a brand name. But whatever the PA system, come on you supermarket workers, why do you speak in that daft voice? I'm willing to bet that you are instructed to speak in that way, as you all do it in the same way. The question is, WHY? It sounds ridiculous and it doesn't make the message clearer.
