I rise in support of my hon. Friend's judicious suggestion. Can he clarify what he envisages under the term ''hat''? A Rastafarian who is asked to remove his hat may claim that it is an article of religious importance. I wonder, a fortiori, whether a Sikh would take umbrage at being asked to remove his turban. Does my hon. Friend think that a turban constitutes a hat for the purposes of his amendment?
