Customers waiting to get service from server are portrayed by queue and also called waiting line. Unsatisfied customer due to lengthy queue can be potential loss to any service organization. In single queue single server, the above mentioned potential loss is higher. So, we deal with single queue multi server. This motivates us for the study among single queue multi server and multi queue multi server which one is best according to the expected total cost. In this paper, we revealed the total cost with assumption of service cost and waiting cost is better in single queue multiple server than multiple queue multiple server in supermarket checkouts counters.
