Mr . X calls your office to see your employer, who has forgotten about the appointment and is now lunching at his club with an important overseas client. How would you deal with the situation?

To deal with this situation, follow these steps:

1. Apologize to Mr. X for the inconvenience caused and acknowledge that the appointment was previously confirmed.
2. Inform Mr. X that your employer is currently unavailable due to an unexpected lunch meeting with an important overseas client.
3. Offer to assist Mr. X by rescheduling the appointment for a more convenient time. Ask for his availability and suggest some alternate dates and times.
4. If Mr. X insists on meeting with your employer immediately, ask if he would be open to meeting with another representative from your office who can discuss the matter in your employer's absence.
5. If Mr. X agrees to meet with another representative, communicate this to the available colleague, providing them with Mr. X's contact information and necessary background information.
6. Send a follow-up email or message to Mr. X summarizing the conversation, including the new appointment details or the contact information of the alternative representative.
7. Inform your employer about the situation once they are available, apologizing for any inconvenience caused and sharing the resolved solution.

Remember, it is crucial to remain professional, polite, and understanding throughout the conversation to maintain a positive relationship with Mr. X and ensure satisfactory resolution of the situation.
