It's the complete loss of control which panics me. It's quite understandable that people also get anxious over maybe forgetting to remove stuff (from their bags which the security wouldn't let through) or rechecking if they've everything. Because if not, you have to run around a lot and potentially miss your very expensive flight with likely no monetary compensation
What an adorable little floofball! Thanks for sharing this, I love it!
