That's rather like the classic I was told about by a friend who used to work for one of the big supermarkets.
One day, they had a phone call - not realising it was hoax, the girl on the customer service desk made the following broadcast announcement to the whole store:
We have a small child lost in the store. His name is Michael Hunt, so, if anyone sees Mike Hunt, would they please come to Customer Services and ask for ****** ****!
Many eyebrows were, apparently, raised.
