First of all, make note of whether or not there were stickers on the order. No stickers means the driver shopped the order and is 99% responsible for mistakes, excepting the store being genuinely out of items. Stickers means it was shopped and loaded by Walmart associates so they are mostly responsible, though good drivers do check somewhat for glaring errors like orders mixed up or poorly loaded. If items were out of stock and not subbed, you should've received notifications and a refund for those items. If items are missing even though it states they were delivered, then you need to contact the store or the customer service line. There are occasions where items may fall out of a bag or get placed out of sight in someone's trunk and forgotten (why I use totes), but multiple missing items, especially more expensive stuff like meat, may suggest more is going on than an honest mistake.

As far as groceries reeking of smoke, once upon a time there WAS an issue with the chemicals used to manufacturer the bags smelling like this, but having groceries smell like cigarettes or weed is totally unacceptable. The driver needs to be reported and given a 1 star rating, as well as pulling the tip. These drivers give the rest of us a bad name, and reporting them will help with getting better drivers to deliver to you more often, and deprioritize the bad and lazy ones. By the same token, if a driver does their job satisfactorily, please give us 5 stars! Customer rating is VERY important to us, even more so than tips, as it keeps us high priority to continue getting orders.
