Turnaround at Phnom Penh (PNH).
Transit desk unmanned and transfer security also.
No OLCI or return check in so I had no BP.
Ground staff took my ticket and passport and went away to get it issued landside. They arranged for someone to open up transfer security for me.
Once airside they escorted me into the contract lounge to await my boarding pass. Documents all returned as boarding was 3/4 complete.
No need for me to enter country (requiring visa on arrival), although I had photo and cash just in case.
