Advice:

One guy bought a complete set of Pepy's Diaries, 13 volumes priced at £350. At an estimate I would guess the customer's age to be 65, maybe older. 'Fascinating man', I said when loading the diaries into a box after he had paid. 'Stupid bastard more like, writing all this nonsense', he said. 'He achieved a great deal though', I added. 'Would have got a lot more done if he hadn't documented every shit he'd ever taken.' I had neither the will nor the passion to resist. 'Ok', I agreed, though I wondered why he was buying the books.
