Maybe. Maybe not. This is Thailand, and the price is whatever you agree. He may welcome a night in more comfort than he gets at home, or he may want to get home to his family. You don't know.
Don't overthink it. Although it's good to have some idea about how things usually work, your questions read as though you believe (maybe only subconsciously) there is a rigid set of rules and if you ask enough questions you will achieve certainty. That European mindset doesn't work here.There are no such rules, just some cultural assumptions (and maybe cross-cultural misunderstandings!), and every encounter is different.
