Whether the contract is one which involves personal taste or not, a provision for performance to the satisfaction of one of the parties is not performed if a reasonable man would not have been satisfied under the circumstances.1 A contract for plastering "to the satisfaction of the owner," is not performed if it is so defective that the owner has reasonable cause for dissatisfaction.2 Under a contract reserving to one party the right to terminate the contract if he is satisfied that the adversary party is delaying performance unnecessarily, his determination of such fact is final if not unreasonable.3
