I was staying two nights. After the first night, still in bed, a knock came on the door, at about 9 AM. I opened the door and a man claimed to be maintenance and said he needed to change the alarm battery. He said his name was Mark. I let him in. He took a chair, stood on it, changed the bulb, and on his way out, said "You're welcome," in a sarcastic manner. I was still sort of in sleep mode and was unable to take in what was really happening. His remark seemed unnecessary and rude.
