I already verified your F10 clearance and have some questions ka. I understand that you paid travel expense to meeting participants. For participants from ต.ถ้ำลอด อ.ปางมะผ้า, I have checked distance from below website and got 65.41 km. so the whole route would be 130.82 km. x THB 4 = THB 523.28 while you paid THB 600. Please kindly clarify ka.
