Dollar Tree

I have a problem with employees not wearing masks while serving customers and walking around the store. The sign on the door says masks are required for customers when entering, as most business do. However, at the time I entered the store (7:15pm) there were two employees working int the store, and neither were wearing masks. The one who checked us out was eating and drinking at the register. I think masks should be required for employees as well as customers and better monitoring of employees should be in place to make sure rules are being followed.
