They’re not just taking up store space. Retailers say the machines interfere with remodeling plans and expose them to potential safety hazards and liabilities. Some kiosks are hardwired into stores’ electrical systems. Outdoor machines are bolted into the concrete foundations and contain a coolant that is supposed to be disposed of in an environmentally safe manner
I’m guessing it’s for the outdoor units so the discs don’t get damaged. They wouldn’t need any AC indoors.
