Charlie and the Chocolate Factory Rules and Order Quotes

How we cite our quotes: (Chapter.Paragraph)

Quote #1

"On this day, and no other, you must come to the factory gates at ten o'clock sharp in the morning. Don't be late! And you are allowed to bring with you either one or two members of your own family to look after you and to ensure that you don't get into mischief. One more thing – be certain to have this ticket with you, otherwise you will not be admitted." (12.20)

Of course, now that we've read the book, we know that most of the parents don't even come close to making sure their kids don't get into "mischief." And Charlie, the one kid who doesn't get into trouble, was never once tempted during the tour.

Quote #2

"But do be careful, my dear children! Don't lose your heads! Don't get overexcited! Keep very calm!" (15.1)

Wise advice from our Mr. Wonka. Of course it's immediately ignored by just about everyone (besides Charlie and Grandpa Joe).

Quote #3

"Oh, no! Please, Augustus, please! I beg of you not to do that. My chocolate must be untouched by human hands!" (17.1)

Now there's an interesting rule. Why must Mr. Wonka's chocolate "be untouched by human hands"? Is it because of germs? Or does Mr. Wonka have some other reason for this rule?
