A little off topic, but, I was pulled aside after collecting a hard rifle case from oversized baggage and not having declared anything. Customs officer approached me and questioned what I had in the case (before I got to the exit of the baggage hall) . I responded that I had my dirty underwear in it. Nevertheless I was sent to the inspection area and was asked to open the case. He was very shocked to be confronted with about 3 weeks of dirty underwear
You'd think they would already know what's in the case with their xrays lol
