Has anyone ever attempted to do what the local minivan-visa-runner-drivers do, and bribe an immigration dude at the kiosk? As in, I need to enter Thailand for three weeks or so after holidaying in Malaysia, via Sadao (overland where they only give a standard 2 week visa) - do you think if I slipped a 100bt note in with the passport and asked for a 3 week stamp, he'd do it?
Or would I be likely to get something else...?
