(ii) Pure Services
An alternative category of services is those which leave no end product, known as ‘pure services’, such as the provision of lessons and entertainments. Beatson has argued that, because of the absence of an end product, such services cannot constitute an enrichment, except where the defendant has been saved a necessary expense. But this is to adopt a highly artificial definition of enrichment, grounded upon economic principles, which is contrary to common sense. The provision of pure services can be objectively beneficial since reasonable people are prepared to pay for them, and so they should be regarded as an objective enrichment, although this will be subject to subjective devaluation. Pure services which leave no end product have been recognized as a relevant enrichment, such as the removal of sewage and the policing of a football match.
