Fair is matter of interpretation, as is law.
As long as you stay out of the country or don't break any law or don't end up to any civil case with local while here, you are likely treated fair. But if you break any of these, and end up to the legal system, against a local, odds are that you will not be treated fair in your mind, though the other party might disagree. At the end, you are at fault as if you would not have come to thailand, the issue would not have happened in the first place.
