(A) Whenever inspections of the premises used for or in connection with the operation of a licensed business or occupation are provided for or required by this Code, or are reasonably necessary to secure compliance with any provision of this Code or to detect violations thereof, it shall be the duty of the licensee, or the person in charge of the premises to be inspected, to admit thereto for the purpose of making the inspection any officer or employee of the Village who is authorized or directed to make the inspection at any reasonable time that admission is requested.
(B) Whenever an analysis of any commodity or material is reasonably necessary to secure conformance with any provision or detect violation thereof, it shall be the duty of the licensee of the Village whose business is governed by provisions to give to any authorized officer or employee of the Village requesting the same sufficient samples of the material or commodity for the analysis upon request.
(C) In addition to any other penalty which may be provided, the Village President may revoke the license of any licensed proprietor of any licensed business in the Village who refuses to permit any officer or employee who is authorized to make the inspection or take the sample to make the inspection, or take an adequate sample of the commodity, or who interferes with the officer or employee while in the performance of his duty in making the inspection. Provided that no license shall be revoked for the cause unless written demand is made upon the licensee or persons in charge of the premises, in the name of the Village, stating that the inspection or sample is desired at the time it is sought to make the inspection or obtain the sample.
