the stories are for people with extended travel history into the country, is it your first time coming to Thailand? Then you have nothing to worry about as Jan said in comments show your exit flight in 8 days if asked for it. Enjoy 😊
I have to agree with what Brandon says, either you meet an IO with a good hair day or not.
Are you over 50 you can apply non-oa based on retirement, if under maybe invest in a tourist visa and have what you need. Booking, 20k and an exit flight.
