You arrive at work in the morning and discover that an important client meeting will start in 30 minutes. Your manager is sick, the presentation file is missing, and the client has already arrived early.
First, I would stay calm and organize the situation. I would ask one coworker to welcome the client and offer coffee, while I quickly prepare a simple presentation with the available information. Then, I would ask the other coworker to help find the missing file. Finally, I would apologize for the delay and start the meeting professionally.
