Not really a question as much as an answer hopefully for people wondering or worrying about getting a visa from Thailand going into Cambodia via the Poipet crossing. I was ready for scams but there were a few trick plays they threw at us that we were not ready for. I have put a draft chapter from my diary on my website if you need some advice, it will tell you what to expect, especially as the trains aren't currently running. As I post this happened 3 days ago.
Hope it helps
