In this case, A.S. received a tip-off that someone was smoking in the hotel. Or if this happens in a hotel, there will be periodic door-to-door inquiries on A S, and if there is any abnormality, it will be checked. Or you're unlucky. Just now, a man with a criminal record checked out, and you will check in as soon as you move in.
