Lack of service delivery. Poor service

Two consultants/cashiers available with almost 15 people waiting, helped 3 people in an hour. Just when you get to the front they close the blinds in your face and tell you, 'Sorry, its lunch time' it is extremely poor. How can only 2 people operate on a busy day? Then you have to wait anothe 15 min for a second person to replace the one on lunch. Poor poor poor
