In the event it is brought to the attention of the city council that a violation has taken place, before revoking or suspending such license, the city council shall cause notice to be served upon the licensee, setting forth in general terms of the violation or violations claimed to have been committed and such notice shall provide a time for the licensee to respond to the allegations. The city council may revoke or suspend the license if the city council finds that the license was issued in error or that licensee has violated the provisions of this chapter and no refund of any unused portion of the license fee shall be made to the licensee.
