Arrived into Bali Thursday night and my bag came out on the Carousel with a pink wiretie on the handle. Travelling with 2 other people and no wireties on their bags. I knew that I had wine in the case that was tagged. As we approached the x ray machines I noticed several other passengers with wireties on their bags. Those with wireties were directed to the x ray and those without were just sent straight thru without being x rayed. I remember the old days of the white chalk cross being the signal but I suppose now in the days of hard plastic case cases chalk marks are easy to wipe off, but a wire tie is not easy to cut off unless you managed to hide a knife on you.
