I'm just saying, when you run into some people who claim to be classical musicians but who don't look or behave anything like any musicians you've ever heard of, who are travelling on an unusual schedule with unusual luggage, who ask a lot of oddly-specific questions about security, who seem overly concerned with whether or not a large crate will get X-rayed, and who offer you large quantities of cash for unclear reasons, it's worth at least a quick ping to airport security.
