There's two lines I don't really get:

"What do you want for tea?" "I want crisps."

Can someone clarify this?

They're from England. The English call chips, like potato chips, crisps.

... and "tea" is what we call the main evening meal in England. Not to be confused with dinner, which we eat at lunchtime. So these kids don't eat properly, they hang around the streets and live off crisps. And they don't talk to coppers.
