No problems, the usual beggars.
On the Cambodia/Vietnam border, you get guys trying to pick up your luggage to carry to the bus area, then try and demand $10 for doing it, it was about 150 yards! Gave him a dollar and told him where to go, I told him 5 or 6 times to put my stuff down before we even started.
The Thailand/Cambodia border was plain sailing.
I forgot, we stayed a night at a place called Koh Kong just inside Cambodia, on our way through. God that was grim, don't do it.
We found some digs for the night, dumped our stuff and headed out for food and a few beers. Had some grub at a roadside stall, whereupon rats the size of small cats were running around. After we finished eating, the lady running the stall offered her two adult daughters to us as dessert for $5 each! As anyone would do, we made our excuses and left (think the brides-to-be on East is East!).
Then we headed off to find a bar for a few beers, eventually coming across a likely looking establishment with a couple of tables and chairs, so sat down and waited to be served, nobody was in sight. About 5 minutes later a guy walked in and jumped back, looking shocked he had customers, despite the language barrier, ordered two large beers and sat chatting, enjoying the rest. Then a bat flew in and spent the next 10 minutes flying round and round the room, getting lower until it tired so much, it flopped on the floor and was promptly seized by another fkn great rat and carted off! We sat and had another couple of beers before heading off back to our room.
On the way back past where we had previously eaten, the lady asked us if we knew the guy that had served us the beers. We both thought it was a weird question and replied in the negative to which she said: "Oh ok, so why you go his house and sit for so long?" Turns out we had wandered into some poor unsuspecting Khmer guy's actual home, no wonder he looked at us strange when we asked for some beers! Still, we left him a decent tip and the beers were only a dollar each!
