A nature valley bar, some Goldfish crackers, and some carrot sticks. This is what I generally munch on everyday and I know it won't make me lethargic or make me sick.
Almonds and dark chocolate. Last year, I took a Chewy bar, and the people in the front had me take it out of the packaging and place it in my plastic bag (same with my plastic water bottle label).
Do you mean that your other option would be to take the snack (lets say a protein bar) out of its packaging and put it into a clear sandwich bag? If I have interpreted that correctly, I find this to be an odd ruling.
