120 It’s Too Late

A mother and her child are walking along the street.

（C=child； M=mother； W=waiter in a restaurant）

C： Mom， I need to go to the washroom.

M： Uh-oh！ Can’t you wait？

C： I can’t stand it anymore.

M： OK， let’s go into this restaurant. Excuse me， but can my son use your toilet？

W： Of course not. This is a restaurant， not a public toilet.

M： You’re so mean.

W： Oh， OK. But it’ll cost you US$5.

M： What？ That’s highway robbery.

C： Mom， never mind. It’s too late.

W： Hey， come back here and mop the floor.
