My father worked for AT&T Int. and we went all over the Orient from '80 to '92. Korea, Japan, Hong Kong, Thailand, Indonesia, Malaysia, Singapore, all over. You name a country on the Pacific Rim, I've been to the airport AT LEAST.
Malaysia was my favorite, tho. We camped in the million year old rainforest, golfed on the royal golf course, scuba dived the rock quarry lakes, and mingled with the culture we found there.
But yeah, all of the English speaking people in that stretch of Southeast Asia were speaking English that the Brits taught them. That's why I often say "telly". I refuse to spell color as colour, tho, don't know why.
