Had a funny incident the day after I got married in POM in 1980. My wife of a few hours visited Dept of Immigration at Waigani to change all her paperwork etc.
She came home crying saying that an Immigration Officer wouldn't return her passport...(my wife was Latvian and had breen brought up to fear Officialdom - until she met me!!)
Meanwhile I had received a telephone call from this Immigration Officer, who I knew from working at the airport, telling me that a woman had visited him masquerading as my wife (the guy knew that I was single - then). I put him right.
And my wife put me right in no uncertain terms!!!
There wasn't much to laugh about in Immigration in those days as we all know, but at least they got a laugh that day.
