Siem Reap
A banner in front of a temple. Back when I worked for an airline in Bangkok, I encountered a fair bit of human trafficking. If an inadmissible person was sent back to Bangkok, we were stuck if they did not have their real travel documents with them because they could not reenter Thailand. The most common solution was to send the trafficked person to Cambodia. The syndicates who smuggled them would send a runner with the trafficked person's real passport and a one-way ticket to Cambodia. From Cambodia, they would once again make their way back to Bangkok for another shot. It was a bad situation, and one where I was helpless to do much.
