Wrong hotel room.

Date: 7/25/2019

I was in my local pub due to some special event. I had this red envelope with "room 16" written on it and handed it in to a woman that worked there. She opened it up and gave me a plastic card for a door. I followed the arrows and found my room. I opened the door and somebody else was living in there. I left and asked a member of staff to check my room number. She held my card to the light and it showed a number. My room number was "61" not 16. So I went and found my room.
