Had an interesting experience at HND duty free this time-- clerks were reluctant to put my liquor in the tamper evident bags (for my onward connecting flight) and insisted I needed to place it in my checked luggage or I'd have to surrender it at security in the US. Only after promising both to put in my luggage after landing and not to blame them if I did lose it, did they seal it up as they've done in the past.

Of course no issues at screening. In fact, screeners returned my package after it went through the xray without additional liquid screening. I wonder what happened. Someone opened their tamper evident bag? Opaque bottle of sake? Receipt dated in the "future" and denied by TSA?
