The thing to remember here Jack is that if somebody does something that pushes your buttons then you must realize that they are “your” buttons. They belong to you. Own it and realize that all you have to do is get rid of “your”buttons. Get up and close the door and be happy, live longer.
I’ve always been asked to show proof of departure… until this year, when they took my word 🤷♂️ it’s usually asked prior to issuing you a boarding pass in your home or departing country.
They want you to get a proper visa now before you enter. So just get a proper visa before you arrive. (*Not the visa exemption you get on arrival) and you will be enjoying Songkran without any worries. 👍🙏
