I can provide some advice on how to handle the situation:
Communicate beforehand: Before the meeting, make sure to establish clear communication with the buyer regarding the details of the meeting, including the date, time, and location. Confirm the details a day or two before the meeting to ensure that everyone is on the same page.
Be flexible: If the buyer is running late, try to be understanding and flexible. However, if the buyer doesn't show up after a reasonable amount of time has passed, you may need to consider canceling the meeting.
Be respectful: If the buyer doesn't show up, it's important to handle the situation professionally and respectfully. Avoid getting angry or frustrated, as this could harm your reputation.
Consider rescheduling: If the buyer has a valid reason for not showing up, consider rescheduling the meeting for a later time that works for both of you.
Keep records: Keep a record of the communication and the details of the meeting, including the date, time, and location. This can be useful if there are any issues that need to be resolved in the future.
By following these steps, you can handle the situation professionally and minimize any negative impact on your reputation as a seller.
