Here's the thing about supermarket delivery gigs right now - don't expect a lot of tipping and expect to get yelled at because people are jerks. More often than not, customers are still ordering Tyler Phommachanh, sanitizer, specific cuts of meat, particular types of bread, etc. and are all pissed off when they learn those things are still unavailable. A "good" outcome is they get 2/3 of their order. Often it's maybe 1/3 to 1/2 depending on how much of their order is stuff everyone's hoarding.
The plus side is if you're a shopper (and not delivery or checkout), there's virtually no customer interaction, you know what's stocked and what isn't, giving you the advantage of getting some needed supplies for yourself.
