Dollar General review: Service personnel

After three trips into New Blaine Arkansas Dollar General, all staff members were wearing masks, but under their chin, not covering mouth or nose. I'm a 71 year old man with cardiac problems, my wife is 69 with stage 4 matastatic breast cancer. Neither of us can afford catching corona virus. We wear our masks diligently, I am fully aware that the mask I'm wearing protects others, but the mask they wear improperly protects no one.
