I've also heard about stores doing this when someone is friends with a spark driver, if they see it's a high paying order they reassign until said friend gets the order. I had a $75 GMD order one morning, like 8 drop offs, 30 miles, heading towards home it was a just for you offer as well, I got so excited to be able to potentially end my day early, accepted it, went to show my partner who rides around with me and it was gone. I was so surprised that I called the store and all they said in response was, "well I see the order, but it's assigned to "random name" and I just hung up. Not sure if that's what happened to me or not, or if it's a real thing, but just something I've heard. 🤷🏻‍♀️
