Jersey Mike’s complaint: employee not wearing face mask

Hello, first of all, I want to tell you how much I love Jersey Mike’s subs. I am an Italian American and you know how to make an Italian sub.
On Thursday, 12.302021, I went to Jersey Mike’s Subs
265 Baltimore Blvd., Suite 3, Westminster, MD 21157
All employee’s were following the Maryland state mask mandate; except one. He was working the grill and pulling bread to make sandwiches. This employee had the mask around his neck. His mouth and nose not covered. I asked one of the employees why?…as all employees were wearing a mask properly. One employee responded he just will not do it. This is a state mandate and should not be allowed. I did tell the store that I am reporting this stores. I am first going to let you know and next, I am going to report this to the state. This young man has no business breaking the law and possibly causing people a serious illness. I will revisit this store, and I hope I do not see this again. Why is the management allowing this?
