As a bit of a follow-on to Buksi's post..the guy that 'lingers' around the Phu Nam Rong Immigration post..IS working with the immigration there.
He has the green-coloured coffee shop there, a Dutch national, & is indeed there to give helpful advice, & generally help out with any problems any folk may have.
There is a 'chubby' Thai man that mooches around there also..he does not wear a uniform, but is there as a 'helper'.
And now for my 'tip of the day' from our friendly Dutchman...
...ALWAYS try to arrive AFTER lunchtime..say 12.30 at the earliest, & try avoid Sunday mornings, so avoid morning arrivals..THAT'S when the border is busy with migrants going each way..
....
(ps..the fee is now 910B there.)
(pps..seen as I've not whinged or ranted here I'm off to find another thread..
