A and B Are Neighbours

A and B are neighbours. Before A left on a holiday, he asked B to "keep an eye on his house." While A was on holidays, B noticed that A's lawn was in need of cutting and proceeded to cut the lawn. On A's return from his holiday, B demanded $10 for cutting the lawn. A's statement was a request for service, and hence B may claim for his service of cutting of the lawn on the basis of quantum meruit.
