Grogan, a marketing consultant, was hired by Kreger Bottling Company to conduct market research into the taste preferences of consumers in a major city. Before he concluded the project, he was asked to take on the additional task of analyzing the appeal of various shapes of bottles that Kreger was considering for a new line of soft drinks. When the taste test was fi nished, but before the second project was completed, Grogan submitted his bill for the taste test.

Kreger refused to pay until the bottle test was completed. Does Grogan have a basis for demanding payment for the portion of the work done?
