Same thing at our local Walmart supercenter. We have so many self-serv stations now that one doesn’t have to wait very long.
The person that monitors the self-serv takes care of alcohol purchases and special situations.
I have to tell you that Walmart does an EXCELLENT job at curbside pickup, I started ordering ALL of my groceries on line I can sit in comfort of my home at do my shopping on Walmart’s website I do this over a few days if I see I am out of something I add it to the cart!! I started doing this BECAUSE if I go into the store I start throwing unnecessary items into my cart and I can’t afford to do that anymore!! When I am ready to get my order I just push what time on that day I would like to pick it up, they notify me of any substitutions and I can reject them if I don’t want the substitutions!! I have been doing this now for about 6 months every 2 weeks I have NEVER had ONE mistake the produce has always been GREAT, meats chosen have ALWAYS been great, they bring the bagged groceries out to the car load them up and off I go!! I have saved a TON of money by not going into the store and spending unnecessary dollars!! Walmart has curbside pickup MASTERED and I thank them for it!!!
