I don't have this one - yet (!) but it occurs to me that whereas a 'normal' person might need a valid reason for walking around with a plate, a slighly 'odd' entertainer can get away with it as they're expected to do strange things without offering any explanation.
Stories such as, 'I went to one of those cheap resaurants yesterday where The Daily Special was the the cold platter for £3.00. And that's all I got - the cold platter, no #@% food at all!' might help explain - or not. (I'm thinking Joe Pasquale here for some reason!).
