One needs to pass the interview at the border with the immigration officer who has the final say. The immigration officer at the border has the right to refuse entry if he/she believes the foreigner is attempting to enter Thailand with a tourist visa for purposes other than tourism. That would be illegal use of the visa previously granted at a consulate or embassy.
