Hawley owned a buick, and occasionally had work done on it at the hoff garage. one day he drove up with a flat tire, parked his car beside the garage, and called to hoff that he had a flat tire and would be back in an hour. hoff fixed the tire. hawley refused to pay, saying that he had intended doing the job himself.
(a) was there a contract? explain.
(b) suppose hoff also adjusted the carburetor and straightened a fender. could he recover for this? explain
