Overheard a mate of mine calling for taxi clearance at Elstree last year...
Mate: "G-ABCD, request taxi for Denham"
Controller: "Taxi for Denham? Do you want a taxi to Denham or wish to taxi to the runway...?"
Mate: "Request taxi for Denham"
Controller: "Errrr.... taxi down to the apron and ask at Firecrest for the number of a local firm"
Mate (now realising his mistake in request): "Oh! See what yer mean now! No, I would like taxi instructions for a VFR flight to Denham"
Controller: "Thought so"
VFE.
