I order from Amazon Fresh, and have since way before the lockdown. I always tip. I ONCE reduced a tip, not to zero, but by 50%, because instead of bringing the bags to my door, the driver left them just inside the door to my building. I had to walk up a flight of stairs to get them, which wasn’t such a big deal, but if it hadn’t been for the fact that my dog barked when the driver came in the door, so I looked out the window, and saw the bags coming in, so I went and looked, they would have sat up there a long time, and if someone else took them, it wouldn’t have been as far off as taking them right from my door. Also, the people who pick up trash on the property might have taken them, OR might have brought them to my door, but reported me to the landlord for “littering” (they have no way of knowing whether they are groceries or trash.
Anyway, I left half a tip on the off-chance that the driver may have been in a hurry due to Amazon over-burdening him, or car trouble, or something. It probably would have taken 60 seconds to bring the bags down (it wasn’t a big order).
I have a standing tip of $5, so I don’t have to worry about adding it each time. My orders are usually pretty small, and require only one trip from the vehicle. If I order something heavy, like my son’s diet Sierra Mist, or RO water for my aquarium, or for some reason the bags are extra-heavy when I bring them in, I up the tip.
When something is wrong, like a frozen food being totally thawed because it was not in a thermal bag, this is not the driver’s fault. I handle that by going to Amazon chat and complaining. They usually refund me for the thawed product, and promise to say something to the employees. I doubt they do the latter, but if the food really is ruined, I want that refund.
