Norman Mayor Breea Clark on Thursday urged Campus Corner business owners to comply with the city's mask ordinance as thousands of students return to the University of Oklahoma for the fall semester. Clark, who visited several bars near campus last week, told The Oklahoman she saw "no masks" and "massive groups," adding "half the staff wasn’t even wearing masks." She shared those concerns during a virtual meeting that attracted about 30 owners and managers, and discussed the possibility of limiting hours and capacity if noncompliance continues.
