Could only be in Britain

Ginger, poor B****rd not much look then.
National health specs and walked with a limp?

Tom, I can think of a milion one defences. Presumably you were within walking distance of a chipshop, so it oculd have been anyones chip. Did they finger print it, check it for DNA. You were wearing someone elses top with their name on it.

This would not have gone to court, but you should have thrown the rest of your chips in his face and walked away while he bagged the lot.

The relevent section (87) for the Environmental Protection Act 1990 states

If any person throws down, drops or otherwise deposits in, into or from any place to which this section applies, and leaves, any thing whatsoever in such circumstances as to cause, or contribute to, or tend to lead to, the defacement by litter of any place to which this section applies, he shall, subject to subsection (2) below, be guilty of an offence.

The verbs "throws down, drops and deposit" imply a deliberate action. The litter warden would need to prove that you deliberately and knowningly dropped the offending chip. Your defence would be that you had intended to eat the chip and there was no intent to cause litter. A judge would thow the case and the chip out of the court and severely repremand the Local Authority.
