In response to a telephone inquiry, Vincent's Tree Service offered to trim an apple tree on the lawn outside the front lobby of the Olde Tyme Prime Rib restaurant, for a fee of $$500.$ Mr$.$ Wilbert, the restaurant's manager, agreed to the price and a start date of Monday. At noon on Monday, Vincent's informed Mr$.$ Wilbert that the job was completed. The tree trimming went fine, but a large quantity of branches and leaves from the tree were left neatly piled near the tree's base. When Mr$.$ Wilbert inquired about the removal of the debris, Vincent's stated that removing it had never been discussed

and was not included in the quoted price. Mr$.$ Wilbert agreed that the topic of removal was never discussed but stated that it is gen, erally assumed that when a company trims a tree, it will remoyp the brush it generates; therefore, he refused to pay until the brush was removed.
