Do angry people have angry birds in their pockets?

I'm in a Supermarket in Cape Town.

I "check out".

I get given two little containers ("packs") that say "Angry Birds" on them.

I don't want to put "anger" into my pocket and take it home with me!

I say: "I don't want anger in my pocket. Do you have peace birds".

The tellers laugh.

What's wrong with society anyway?
