Think yourself lucky.
It used to be the same here in Pattaya 20 years ago but not anymore, today it's hop on your bike, make another appointment.
It's all the angry, cranky, miserable foreigners that have made it so much more difficult, gone are the days when they used to overlook the imperfections, the office staff have been abused too many times.
It's sad but these days if I get asked, 'what's the worst thing about Thailand', I reply, some of the foreigners.
