That was a sticky note, attached to an empty plastic tea bottle sitting on my desk in my hotel room.
Ignoring the Engrish, what's funnier is that they thought it'd be easier for me to find a pen and check a checkbox (on a curved surface), rather than just picking up the piece of garbage and throwing it away in the trash under the desk.
Or funnier: that they thought I'd want to keep the empty plastic bottle. Yes, an important guest belonging for sure.
