That form you filled out in BKK was a cracker especially as you mentioned if you were the last one through..
One of funniest things I saw on arrival in BKK was when the young and hip crew made jelly shots for the bus....non alcoholic of course....or so they emphatically insisted to me so I had no reason not to believe them
After picking up their bag's at the carousel with said refreshments in a foam box on top of the baggage trolley it all went south when the foam box fell off onto the floor with these jelly shots bouncing everywhere....I don't know what they thought was worse....losing the jelly shots or explaining to customs what they were....
In the end I told customs it was one of the girls birthday (luckily it was) and we got away without any problems....
