1. You will be present. Being late causes you to not be present when you arrive, diminishes integrity and causes stress.
2. The person you are meeting might be offended. Yes, traffic happens and nobody is perfect, so being late will happen from time to time. However, people could feel that your time is more valuable than theirs. Communicate your tardiness as soon as you know, and thank the client for waiting.
