Went to at 11:15 and there is lady at the donut and ice cream counter who chewing a chappies while serving clients with food. How do you serve customers and work on their food while chewing a chappies and supervisors saw nothing wrong with a person who is chewing chappies without wearing a must dealing with clients foods. While chewing a gum with your mouth wide open your saliva all over there show. 🤢🤢🤢🤢🤢🤢🤢🤢🤢🤢🤢 How do even buy donuts and ice cream with such unprofessional behavior
