Pack your patience! Unexpected disruptions happen all the time—whether it's a nationwide computer system outage or an intense storm in the Drake’s Passage (both have actually happened to me!). The absolute best thing you can do is take a deep breath, smile, and show kindness to the staff working to resolve the issue. Staying calm gives you the mental bandwidth to figure out your next steps, and a warm smile can make a world of difference to a customer service agent who is likely having a very difficult day.
