I started using the emailed receipt only as the pick up time and no longer go into all the variations of time explanations on my report. And they have been accepted. As @Morledzep noted, there is a disconnect between them. Because the App (or if using their website directly), issues a time once the order was placed. Then the email adjusts the time when the location gets their notification during those seconds of transmission. When the associate finishes boxing and placing your order in the bag, they scan that tiny sticker attached to your bag and that triggers the text message that your order is "truly" done.
I sit in the parking lot and order. At the time the "email" notes as the pick up time, I literally start walking toward the door and step inside on the exact "minute and zero seconds" mark. I record myself stating: "I am stepping inside now." The recording continues, so I have the exact minute and seconds of any greeting, receipt of order, and parting comment, etc. So, I do not have to keep looking at my device or watch, etc.
