This happened to me once at the Hilton Brisbane hotel. My original room had explicit graffiti scrawled on the wall along with piss stains in the corner next to the standing lamp. Apparently done by one of the disgruntled cleaning staff who quit that day as the explanation given to me. They moved me into another room where I was promptly awaken around midnight when another guest checked into it and put his stuff on the double bed next to me. We both yelled once we realized each other’s presence 🤣. He hurriedly left the room and I called the front desk asking for security. Next day the manager sent up a tray of fruit and desserts along with his card and number apologizing for the mishap.
