"Exception: Access is always required for kiosks used by the public. For employee-only kiosks, a "broker" kiosk requires a five-foot turning diameter due to potentially more than one person working inside; "vendor" or one-person working kiosks can delete the fivefoot circle as long as the door is wide enough for a wheelchair and the employee can back into the vendor kiosk and work from within. Also, when only employees use these vendor kiosks (never the public), then ICC/ANSI A117.1 or ADA-AG complying entrance platforms and ramps are not required; rather, a portable ramp stored on-site is an acceptable alternate."
