Over 40 years in this wonderful country I've read and heard about lots of money being stolen by bank staff.
With the current drastic state of the economy and so many Thais in debt to banks and loan sharks don't trust the banks in this country.
Thai Government has said and repeats every year they'll glamp down on loan sharks. If they were serious it would be easy. Pick up the business cards thrown out every nite by loan sharks all over town, track the mobile number and arrest them!
Second thoughts sorrow realised they're mostly run by law enforcers and people in high places. Extremly dangerous people who often resort to violence to get money back.
