This puts me in mind of CEM Joad, a famous 'brainy bloke on the BBC' in the 1930s and 1940s. He liked to be called 'Professor Joad' although he never was one. In 1948 he was caught travelling from Waterloo to Salisbury without a ticket, hoping to short-fare to Exeter. He was fined £2 and ordered to pay 25 guineas costs, in total £28.5.0d, £28.25 in new money. Apparently he'd been doing it habitually for some time and the railway had set a trap for him. It made headlines, he was sacked from the BBC, and lost the chance of a peerage. What cost £28.25 in 1948 would cost £913.66 in May 2026, according to the Bank of England.
