13-3-603. Nonpayment of instrument when person influenced by alcohol or drugs. Any bank may refuse to pay any check, draft or order upon it if the officers or owners of the bank have reason to believe that the person signing or endorsing the instrument is or was so under the influence of alcohol or drugs as to make it doubtful whether the person is or was capable of transacting business at the time of signing or endorsing the instrument. No cause of action accrues against the bank by reason of the refusal of a bank or officer to pay an instrument under this section.
