You're missing the point. This is
criminal law and many people have had their lives blighted by criminal records for dishonestly obtaining lower-value items than a glass of Champagne and two sandwiches.
While BA may well not sue for damages (the civil remedy), an officious staff member has only to report it to the police for them to do the rest. Unlikely, perhaps, but eminently possible. Just like the chance of being caught fare-dodging on the Tube...

Assume they wanted to sue you...under English law (and unless there's some obscure exception somewhere) they are not entitled to punitive damages...will they file a claim for 2 bacon baps and a glass of Bolly?
