Challenge: Handling Customer Requests

You are tasked with managing a customer support system where customer requests are handled in the order they arrive. However, high-priority requests must be added to the front of the queue. To achieve this:

1. Initialize the appropriate data structure to maintain the queue of customer requests.
2. If the required data structure needs to be imported, include the appropriate import statement. Otherwise, remove the import line.
3. Add regular customer requests to the end of the queue.
4. Add high-priority customer requests to the front of the queue.
5. Process requests in the order they should be handled (removing from the front).
