I understand that certain airlines now make applicants write a short essay with pen and paper when attending for interview. Without the 'benefit' of a spell-checker....
'Yoofspeak' or 'txtmsg' acronymish are totally unacceptable. Give up listening to trash broadcasting and concentrate on correct use of English would be my recommendations.
"Nah, mate. 'Sdoin' me 'ed in, this" will not cut the mustard these days! Neither is the ubiquitous yoof word "Cool" an acceptable interjection!
