For those interested in this crossing - it's an interesting one as the Cambodian guards are still on the take. Quite funny though
Lao side ask for a $1 US to get the passport stamped
(a) you can get away with giving a small amount of Kip and say you haven't any other $'s
(b) pay up the $1US
(c) don't pay - then they wont stamp the passport - you go to the Cambodian side and they wont take you and send you back to the Lao side - they laugh (especially when it's hot)
Cambodian side - now this was a laugh
(a) got out of bus and a small tent setup on side of road with (probably a guard) with a Dr's mask on and some other people. They go to take your temperature with an ear thermometer, but he points it at your forehead from about a foot away - no wonder all the temperatures were the same. They give you a piece of yellow paper written in Cambodian, which basically says your clear to go through.
YOU DON'T NEED TO DO THIS, IT'S NOT NECESSAY
You get to the Cambodian stamping office
(a) got passport - they ask for the $1US or wont stamp passport. You can probably try the "I don't have the money, but when we were there the guard just walked away and wouln't stamp the passport (he still held it) came back about 20 mins later and the same process again. Some Brits tried this and wanted a receipt - all to no avail.
(b) Haven't got a Visa then $20US also with an Admin fee to pay of $3US to process it, then back to the $1US above to get through.
A relatively simple exercise became a 2hour 20 min crossing
