What does a auto repair shop need in Cook County that other businesses do not?

Weights and Measures Device Inspection — State and Chicago Programs (Cook County)

No fee applies at the Cook County level. Under the Illinois Weights and Measures Act (225 ILCS 470), § 10 directs the state Director of Agriculture to inspect and test, at least once every 12 months, all weights and measures in commercial use, and § 9 provides for cities that appoint their own sealer of weights and measures. A commercial scale, gas pump or other measuring device used by a business in suburban or unincorporated Cook County is therefore inspected by the Illinois Department of Agriculture's Bureau of Weights and Measures, and a device used by a business inside Chicago is instead inspected under that city's own program run by its Department of Business Affairs and Consumer Protection. Because the statute places these inspections with the state and city sealers, there is no Cook County fee for either function.
