About 8 years ago, I was in the JL F NRT lounge. My car keys dropped out of my carry-on bag, but I didn't realize it until I arrived at the next destination. So, I figured I was out of luck. But a month later, I was back at the same lounge. I thought, why not ask? I did... and about half an hour later, a lounge attendant (wearing white gloves, of course) brings me my car keys on a silver tray. Only in Japan.
