Today at the drive through they were training a new person who was very frustrated and cussing. My children were scared because she was so frustrated, angry, and cussing up a storm. I was surprised that the person who was helping her didn't show her how to turn off the mic to the speaker box or tell her to calm down and quit cussing. Had to reassure my children that she couldn't hurt them.
