AN email recently circulated showed young men with radiant smiles training to be police officers. At the end of the email, there was a lone picture of a frowning cop. The contrast was made obvious by its sheer starkness. Ask any citizen or resident in any country why they go to great lengths to avoid having to deal with officialdom, and over and above rampant bureaucracy and inefficiency, chances are that they will tell you about how rude, rough and abusive security men and government employees (note that virtually no one refers to them as public servants) can get.

The old saying that a smile costs nothing is an ever
