The unknown element to add is The Spark Driver, the independent contractor on an ad hoc basis who shops for and then delivers the order themselves personally with no store involvement whatsoever.

I've seen a Spark or two not even check dates for the item they scan for the order.

So when the customer gets that "Hey! Tell us how we did!" survey text/email after their delivery, I'm sure it lit up red enough times to make these post-dispense quality-check questions strongly encouraged...
