During filming of the new Antiques Roadshow series, a man presented a glass bottle he had recently bought from an antiques shop. He had paid a considerable sum – more than £1,000 – and felt confident that it was worth more. He was smartly dressed and well-spoken, and appeared to know what he was talking about. The show's glass expert examined the bottle, consulted a colleague, and delivered his verdict. "I'm afraid it's an empty olive oil bottle, Tesco, circa 2008. It's worth nothing at all."
