In connection with the use of any portion of a utility for recreation purposes, as specified in Section 11-123-15, every city and village has the power to provide, by lease or contract, for the sale in or on the utility of food, non-alcoholic drinks, and merchandise, and for the giving in or on the utility of dances, concerts, exhibitions, and other entertainments, and for check-room privileges incidental thereto. Upon reasonable notice, however, such a lease or contract is terminable by the municipality, either with or without compensation therefor as may be therein stipulated, whenever in the judgment of the corporate authorities of the municipality the transportation necessities make such termination desirable. No such lease or contract shall be entered into for a period exceeding 5 years except in conformity with the provisions of Section 11-123-12.
