How do you feel about packaging that doesn't work the way its supposed to?

Please don’t get the idea that I’m a lazy person when I ask this. I’ve just been increasingly frustrated and foiled at every turn by packaging that doesn’t open the way it’s supposedly designed to. You’ll clearly see a red line across the pack on the inside, and there is even a notch where you’re supposed to tear. It says “tear here”. And yet, I can’t tear it! I finally get the scissors and cut right over the red line, and the package still has half an inch of sealed front and back all the way across! The perforations on the soda box wont allow you to poke through without tearing through where you’re not supposed to, and if you try to grab the front and back of a bag of chips to pull the top apart it won’t pull! Wont! I don’t know what they’re sealing chip bags with now, but it must be designed not to open, like some bizarre x-files conspiracy, they want you to have an untidy opening. The same can be said of cereal bags inside the box, and the box is about the only thing left that still opens properly. Cling wrap, foil, any of the boxes with rolls inside tear so that the whole roll is difficult to tear off. Food in plastic pouches with snap-seals are pointless because the seal piece comes apart from the inside of the pouch.
Enough! I say, stop charging me extra for handy dandy resealable packaging that doesn’t work, and I’ll just put it in a sealed box or bowl or bag myself. Is it just me? Does anyone else have a hard time getting at food or other products sealed in plastic?
