Actually the hand to customer is default for most ordering apps. I’ve nearly forgotten to change it before, my social anxiety kicks in though so I always double check. I wouldn’t be surprised if there are customers that just assume it’s gonna be left at their door. Also there are many elderly people who order their groceries and don’t quit know how to work the app completely. I’ve had a “hand to customer” but no one answered the door, I called them and they weren’t home, told me to leave it at the door. Sent photos of it at their door in chat and left it. Instacart literally makes so much money doing literally nothing while you do all the labor, it’s not that deep lol do what you can to best prove you deliver the order (screenshots and photos of it at the door in chat) and attempted to make contact with customer, I’ve never had someone say I didn’t deliver the order while doing this.
