Ridiculous
They could have easily just told her to throw it away. Its not like she is importing apples of mass destruction. CBP are some of the biggest Aholes on the planet. I had a moron try to fine me 25,000 USD for a STICKER that wasn't on the plane. I had to get his superior involved to point out via email we had a conversation that we would be getting the sticker AFTER we arrived into the great land of the free(absolute BS)
Give some people power and it goes to their heads. The states is a hypocrisy at its finest.
