There is nothing Thai or Buddhist about your experience. It could have happened anywhere.
Years ago after a Goenka retreat I decided to stay behind to volunteer in the kitchen for the next retreat. About 5 times a day, at least, there were situations where I knew how my choice of words would have made a huge difference to the harmony of things.
Halfway through that experience, one of the assistant teachers asked to meet with me in private. She told that she had heard that I had handled some regular, difficult, volunteers very well and asked me how I did it. I explained to her that in college I had worked in a food co-op. It had many of the same types of people and the same types of work as volunteering in the retreat kitchen. I had learned to recognize and avoid certain puddles by having stepped in them many, many times before.
In reading the scriptures, there are two kinds of mistakes:
One mistake is to cling to the literal text and miss the inner principles.
The second mistake is to recognize the principles but not apply them to your own mind, so that you waste time and just make them into causes of entanglement.
