Was wearing a shield but having it up....Crazy woman pulled her mask down just to say Fook You...Manager caught up to me several isle later I pulled out the EO and said right here it says "If the mask is going to cause harm to an individuals health then they do not have to wear it" Manager said then don't wear it....Off came the shield and never will it be on me again!!!!!! Playing their own game on them...Love it!!!!
