Sheetz review: Drive thru

Store #516, my husband placed an order on 3/11/21 at approximately 4:30 am. We pulled up to the window. We waited and listened to the bell for more than 5 minutes and nobody came to assist. We needed a request for our order. We were not able to see any employees at the time. So we gave up and left. Once around the building, an employee was going through his car, we did not stop nor say anything to him. I really don't know how nobody heard the bell dinging at the window.
