Thai motorbike-taxi guys. You'll run into these chaps a lot. They're positioned at major intersections and bus stops where they ferry the locals off home. It's one of those 'male club' sort of things and there's a certain Thai macho-bravado mentality amongst the group but like most things in Thailand, a few friendly words and things open up wonderfully. If you're stuck for words, Mr Pumpy advises pointing at the bike and saying: "Me farang! Me crazy!" - to which they'll readily agree, being motorbike guys.
