Around 15 min from the border, the bus stopped at an official looking building and the conductor (a woman) got all the passports of the Thais. (Is that where they get a day pass?) I asked her if that was where we had to get off to get our passports stamped. She couldn't speak English, and fortunately, another woman (who spoke English) heard and said, no, it wasn't the place. She would tell me when it's time. So I thanked her and sat again.
When we got to the border market, all the Thais started alighting from the bus. The kind woman told me to go down with them. Then told me to return to the bus at "three and a half o' clock" to get back to BKK. I told her that I didn't intend to go to BKK, that I was to go to Cambodia. So she told me, "go 2nd floor, Thai ppl 1st floor". I just followed the flow of ppl, and true enough, there was a sign for foreigners to go to the 2nd floor for stamping.
After the stamping, I walked down the stretch of road leading to the Cambodian side. There were very long lines for the visa-on-arrival. Many ppl approached me, asking if I wanted a visa. I just shook my head and said, no, I didn't need a visa. Then they asked, "where you come from?" So I told them, and they just waved me off to the Cambo side.
That was my first land border crossing - it was very hot, being midday, but it was interesting. The border crossing (Cambo to Saigon) was a bit different, but that's for another story.
In my brief journey, I found that ordinary Cambodians spoke better English than their Thai counterparts. But some were same-same but different.
End of long post. 55
