I can see the headlines now...

Man is assulted over missing cheese piece!

A man was arrested today at an Asda supermarket.
The who has not yet been named, attacked another man namely joe public.
Mr joe public told the local rag that the attacker got in a miff because I
asked the cashier to check the box for any missing cheese pieces as I
didn't want to come back half hour later demanding an exchange or refund.

Possible. I don't know how people behave in Asda....
