You have just arrived in this city and you came to this hotel to get a room for yourself. However, you firstly wanted to go to the restroom. You ask the lady at the desk and go to the restroom. The workers not knowing that you were inside the restroom close the door from outside and leave. You knock and yell for help but you get no response. Probably, your voice is not heard outside. You will now have to look for another way to get out of the restroom. You are angry but try to suppress your anger because anger often interrupts clever thinking.
