2. The traveler who complains nonstop about the wait
The traveler who’s worried about missing an impending flight is annoying, but they’re not alone. Some travelers just want to grumble and grouse about the wait, even if they have nowhere to be anytime soon. This person complains about the wait in the parking garage. They grumble about the line at baggage check. Then they sigh about the crowds heading toward the security checkpoint. So you better believe that once they finally get into the security line, they’re going to gripe nonstop about the wait (even though everybody within hearing distance has been waiting, too).
