AT&T is a telecommunications company with a call centre. When customers call the customer service centre, they are queued up to speak with a customer service representative. Customers are asked to wait and are given a specific number if the operators are busy. A customer's wait time could be as little as a minute or as long as 30 minutes. This also varies according to the type of customer. Platinum customers will receive a higher level of priority than Gold customers. Thus, when a call from a Platinum customer is received, it is prioritised for processing. If there are no remaining Platinum customers in the queue, the Gold customer will be served.
