upto date bank book same day or 24 hours before. which is as daft as a box of frogs.
as if this was all you had. and taken it out via the atm and not updated your bank book WELL. mind boggles
just for the RECORD there is a nice laos guy directly across the road who can get around the requirments. should you be unfortunate enough to forget your docs. this charge is 5000bht . 50% back to the official at the counter. so its not all negative just CORRUPT as per
BOTTOM LINE its dunb as thai regulations nothink more..
sensible approach woilukd be to hand out or show prominent information on thai side. before people get stamped out . . USE THE ATM get a statment etc .
