What should I expect when leaving Thailand after using various visa types?

This is most helpful and supportive group. Thank you for all your thoughts and insights. Last three years I’ve been through work visa, tourist visa, education visa and retirement... it is my few last days in Thailand as time has come to move on. Good luck to everyone and so-long for now.

by the way; Two weeks ago when I came back form Myanmar was stopped at the check point (1st time in 3 years). I believe the same woman, she gave me all kind of comments/questions, including making me to write something in Thai. And wanted to see a ticket out, since I was arriving as a tourist.
