Why must we call when we still have to follow same queue with those who never called???

Pedro's in Chatsworth at unit 5. Horrible service I received first I had to listen to their music while I phoned them for more than 30 minutes before they could answer the phone to take my order. When my order was finally taken I was told to come pick up in the next 30 minutes. To my surprise when I went in to collect I was told to follow the queue with all the people who never called but went straight to the store. I had to wait for another 30 minutes following a queue while I phoned prior which is horrible.
