May I help you?
I would like to return this book.
May I do anything else for you?
I would also like to check out this magazine.
I can't let you do that.
Why is that?
Our policy doesn't allow anyone to check out the magazines.
What things am I allowed to check out?
You are only allowed to check out books or videos.
I really need to check out this magazine.
I'm sorry, but that's our policy.
That's stupid.
