Thom Takes His 1956 Thunderbird to Upholstery Shop for a New

Thom takes his 1956 Thunderbird to Upholstery Shop for a new interior with the agreement that Thom "must be satisfied." When he gets the car back Thom says he is not satisfied because of very small imperfections in the seams sewed on the back seat-the imperfections are not noticeable except on a minute examination. Thom . . .

A) has to pay a fair amount for the job: he is being unreasonable.
B) doesn't have to pay anything until Upholstery Shop does the job right.
C) doesn't have to pay anything at all and can take the car.
D) will only have to pay if a knowledgeable third party agrees the imperfections would not cause a reduction in points awarded for restoration at an antique car show.
