I think the customer service is excellent. However, I am writing a one star review for the drive up and go grocery shopping. It is a nightmare. The app does not work to let them know you are there and

Kid behind seafood counter laid my salmon fillet in between the door and the fish racks on the dirty metal, then the cashier Koki literally told me her arms were too tired so she couldn't pack my bags

Worse customer service ever!!! All of their staff was very rude. I will never shop at this Safeway again.
