In my early 20s I quit my job in New Zealand and moved to Sydney to study martial arts. In 1982, after competing in the World Pugilist championships in Hong Kong, I hitchhiked around Japan for a month or so, then headed for Korea via ferry in January 1983. I’d heard air fares were cheap from Korea. No internet back then!
While boarding, I was approached by a very attractive Japanese woman, with limited English, who told me that if I bought one box of bananas and a bottle of Johnnie Walker Black label, I could pay for most of my trip in Korea. These items were very much in demand back then.
