Muffy,
I see dat you har hasking about da 'ed tes', compass swing, an awl dat stuff. Why don' you worry habout da hinterview, get da job and endless training owt of da way firs', den worry habout da per diem?
An I hepect dat being from Singapore, (Airline or home country?) dat da, ow you say? "Engrish" tes' won' be of any concern eidder because of cor' da hinglish is the primary language of Singapore, eh?
