What should a visitor do if they are running late for their scheduled visit?

The best course of action for a visitor running late for their scheduled visit is to call their host to inform them of the delay. This approach is rooted in the principles of courtesy and communication, which are essential in maintaining a respectful and professional relationship. By notifying the host, the visitor is acknowledging their schedule and offering the host the opportunity to adjust plans accordingly.

This proactive communication can help ease any potential inconvenience the delay might cause, allowing the host to prepare for the visit, whether that means adjusting the timing or having a conversation ready for when the visitor arrives. In many contexts, open communication fosters goodwill and understanding between parties, which is why this option stands out as the most considerate and appropriate response.
