Hi,funnily enough I was never asked to spell "hospital", but I was once asked to spell 'Johannesburg" under the pretence that someone needed it for a crossword puzzle.
Managed to confuse them though.... I stuck in a catholic "haitch" and a protestant "ay". ( some catholics pronounce "a" as "ah". Therefore J.O.Haitch.Ah.ect.)
They didn't ask again.
