They're saying that if you time it right, they won't get/hear the notification that you've checked in and you can slide into the right spot. Wait awhile and then you'll get refunded because you were "waiting so long"

Which it can work TBH, it just won't be a reliable method by any means

I can just imagine pulling up to the nearby “regular” spot when doing pickup and the restaurant/store employee just glaring angrily at me lol
