Ask a foreigner in Bangkok about taxis and inevitably it comes to one thing, why do all taxi drivers let rip the most noxious fart imaginable, once the taxi is under way? Like a stealth bomber, that driver drops a fart, that can leave you reeling and choking in the back seat. I've long given up pretending that I haven't smelt anything. I hold my finger to my nose or whip out my fan In the more horrific cases, I crank the window down and with my eyes streaming, I frantically wave my fan in front of my face.
I have Helene to thank for this picture. She was travelling in a taxi from the airport, when the group she was with spotted this sticker behind the driver's seat.
