Just putting in my experience with immigration. Just some context I’ve been to Thailand now 3 times once for a week on visa exempt, once with a tourist visa and then now on a visa exempt. So when entering most recently the Immigration officer looked at my passport and asked for onward flight or return flight. I had no phone data when landing so I had a screenshot of my onward flight, she looked at my onward ticket from my phone then thought about it for like 2 min then told me wait over there to the side. I knew I was going to be held back. Then another officer said follow me to the “back” room from there there were several of us waiting. The lady said I need to talk to the main immigration officer as soon as he’s finished with another person. Long story short, I waited 30 min then another lady came to me and said why are you here I said on Holiday. She said let me see your onward ticket and I showed her. Then she communicated to another lady and then she asked me why were you brought back here I said I have no idea and she was like who was the officer that told you to come back here and I said I can’t even pronounce your names. She said ok you are good then another officer came over and stamped my passport and I left from there. While I don’t blame the original officer cuz my passport photo and me now are a lot different with no beard and long hair and the onward ticket being from a screenshot I kind of wish the original officer at least asked me questions instead of just holding me back. I think they don’t have time for that since it was jammed packed and would rather have the back officers ask the deeper questions.
