John received a promotion at work and felt new clothes would be necessary in the new position. John went to a local store and charged three ties on his charge account at a cost of $60 each. Bill, a friend of John's saw a sidewalk vendor selling ties at a cost of three for $10 and bought three at that price. The friends compared purchases that night and found they had purchased identical ties. John became enraged and said that he would not pay the charge-account bill because the ties were clearly not worth $60 each. Bill indicated that he would testify in John' s behalf if John were sued. What would be the probable outcome of the lawsuit? Please support your answer with legal analysis.
