I find it quite amusing when US citizens start kicking off when foodstuffs are confiscated or they are fined for not declaring them
I was never aware that one got fined (although I guess there has to be a deterrent), but when going into Dulles last year, I got tagged by the immigration official for a visit to customs extended processing, and other people were in the queue because they'd come in with a banana or other fruit in their bags and discovered that they were in line for a $300 or so fine. I remember many years ago they used to have bins and big warning notices prior to immigration at some airports, they've obviously decided to use forgetful and ignorant passengers as a revenue source instead. The beagles certainly have fun climbing all over the luggage at baggage reclaim.
