I was bit surprised today. I went to my Bangkok Bank branch to request a letter confirming my twelve monthly transfers of 65k Baht, required by immigration for the renewal of my extension. I was expecting to pay around 200 Baht for this. In the event I was charged 700. Baht. Is this about average for the service.
