Generation Y-Help?

(I am at the movie theater. The film has ended and the credits are rolling when I overhear this conversation.)

Little Girl: “Grandma, you made a mess.”

(She points to the huge amount of popcorn on the floor, and gets down to pick it up.)

Grandma: “Get off the floor! It’s filthy down there! People are paid to clean up after us. Let them do their job.”

Little Girl: *still picking up popcorn* “But they have this whole place to clean; we don’t need to make the job harder.”

(The grandma scowled at the little girl and pulled her out of the theater by her arm.)
