can anyone help me understand this event, which I was given as a part of my construction contract studies.
A offered to buy B's car for $1,000. B then sought $1,500 and then A said, " I'll pay $1,250 for it but I must have an answer within a week."
A fornight later B phoned A to say that he would take $1,250. A then said he no longer wanted B's car but B insisted that they "had a deal" which A could not walk away from.
