Ownership of property usually passes when it is paid for, but ownership of food passes when it is eaten – Corcoran v Whent ([1977] Crim LR 52.) (at which point it also ceases to be property) – or possibly earlier, e.g. when it is ordered and cooked in a restaurant. Ownership of petrol passes when it is put in a petrol tank. In the absence of mens rea from the outset, the appropriate charge for this type of offence would be making off without payment under s3 Theft Act 1978 which was brought in to cover those who were unable to be convicted of theft in these situations.
