One of those experiences today, when I wish I'd had my camera. Chiang Mai Immigration, sitting waiting for my turn to be called, and a lanky young falang shuffles in and takes a seat. Tatty clothes, holes in his knees and elbows, dreadlocks, and one of those sticky rice steaming baskets on his head by way of an improvised hat. Everyone near him started holding their noses. Everyone beyond wafting distance openly giggling. And he'd sat down right next to the sign that said "Please dress respectfully".
