Hmmm....

You've never had a block of cheese, two hard boiled eggs, piece of sausage, two apples, and a loaf of bread to feed six people.

You've never had to add oil, break fluid, coolant or wiper fluid, and not had a funnel, but you've been able to find an empty soda bottle.

You've never been confronted with one of those cursed plastic clamshells.

You've never faced a container that is reinforced with nylon strapping. How about tape with fiberglass threads.

You've never watched a coworker actually put his tie in the paper shredder.

Yes, some of these things can be dealt with with a pair of scissors. But let's face it, scissors lack versatility. And the first scenario doesn't do didly for scissors.

On top of everything Blast mentioned, all of which are actually pretty real world. Shelters still have a hard time remembering to bring cots and blankets- forgetting to bring privacy curtains if you have to go to honey buckets is something really easy to see.
