That's the reason they made large hand bags... more room to hide food.
My favorite is mini pretzel dogs which I always sneak in.
Hell no. I bring a book bag, "Got your candy, snack, drink, popcorn, and whatever else." Spend 8 bucks Max. For 8 bucks at a movie.. Hell they're like "One small drink sir"
If you're really crafty you can sneak in your own beverages too. There's no way in hell I'm paying $4 or more for a bottle of water, I have big pockets on my hoodie.
