Most slacker San Franciscans still have Thanksgiving food shopping to do, and many of us who were time-wrecked by the short holiday week still haven’t even started the big grocery pilgrimage. With this in mind, SFist has used Google Maps’ Popular Times feature — which was just updated to show real-time data on crowd size at individual stores — to rank San Francisco’s popular grocery chains by their crowdsourced wait times.

Google’s creepy but insanely useful trove of public, real-time user location data gives us vastly more insight than SFist’s last stab at this Thanksgiving exercise. (You can get even more current real-time data in Google Maps). But there are still some flaws in this feature as a crowd-size assessment tool. Google claims the feature helps you “avoid the wait and see the busiest times”, but length of visit does not necessarily correlate with “busiest times”. Additionally, this list ranks the stores by the grocery chains’ San Francisco averages, not individual store visit times.

But this Google Maps data is still outrageously detailed and allows us to rank San Francisco grocery store wait times from the most commendably short to the most infuriatingly long.

1. Bi-Rite Market (15-minute average visit)
Bi-Rite Market wins the top spot on this listicle because of their amazingly fast 15-minute average visit time. Their stores are efficiently laid-out and the staff seems to genuinely enjoy doing their jobs. Of course the Bi-Rite delivery is also available via Instacart, and Instacart delivers from pretty much all of stores listed below.

2. Mollie Stone’s (16.7-minute average visit)
Mollie Stone’s also scores well as a fast out-the-door proposition, with 15-minute visits at its 18th Street and Portola Street locations, and 20-minute visits at California Street to produce the impressively fast average store visit of 16.7 minutes.

3. Trader Joe’s (19.2-min average visit)
Some TJ’s are more crowded than others. The quickest visits register at the Stonestown “Galleria” and Bay Street locations (15 minutes), with Ninth Street and Hyde Street visits slightly longer (20 minutes), and Masonic Avenue visits the most lengthy (25 minutes), which pretty much jibes with any normal day at these stores.

4. Safeway (19.6-minute average visit)
The one Safeway on Monterey Boulevard averaged 15-minute visits, skewing Safeway’s average slightly downward. All the other Safeways in San Francisco averaged 20-minute visits.

5. TIE- Andronico’s and Grocery Outlet Bargain Market (20-minute average visit)
Andronico’s scores well with relatively short visits! Enjoy Andronico’s while it lasts, they’re getting bought up by Safeway.

Grocery Outlet Bargain Market, whose fabulous radio jingle is forever going through my head, also scores a respectable 20-minute average visit.

6. Whole Foods (21.7-minute average visit)
Whole Foods is very nice. but places in the lower half of this listicle with 25-minute visits at the California, Rhode Island, and Ocean Street locations and 20-minute visits at the Market Street, Fourth Street, 24th Street, and Stanyan Street locations.

7. Rainbow Grocery (30-minute average visit)
Poor Rainbow Grocery really gets screwed by the algorithm here. The place registers 15-45-minute visits via Google Maps' calculation, which is quite a range! That may be likely a sign of their customers’ lengthy contemplations choosing groceries and discussing herbal supplements rather than actual long wait line times.

8. Foods Co (30-minute average visit)
Foods Co, which sells delightfully horrifying groceries at bargain basement prices, is all over the map with average visits of 20-45 minutes at their Folsom Street location and 25-minute visits at their way-down-Third-Street Visitacion Valley shop.
