Is a cold storage facility a "public service" for the public?

In State Public Utilities Commission v. The Monarch Refrigerating Company, 108 N.E. 716 at 720, 267 Ill. 528 (Sup. Ct. 1915), the court held that the operator of a cold storage facility held out its facility as a means for the public to store and preserve its goods: Adequate storage facilities for the storage of goods at the place of destination are equally as important to the producer and the consumer as the means by which the goods are transported to such point. In fact, with the class of perishable products handled by appellant such service is indispensable. … Both those engaged in carrying and those engaged in the storing of the goods alike render a public service and are therefore subject to legislative supervision and control. We could no more do without such agencies than we could do without the railroads or the telegraph or the telephone, and the public is interested in their proper regulation.
