It’s ok, we’re all terrible at this. Science says we’re just no good at choosing the best lines in stores. Thankfully, there’s help available.


Wondering how to cut down the painfully slow time you spend in line at the grocery store? Look no further: here are the top strategies for cutting down on your wait time, according to scientists that have studied the issue.

The New York Times spoke with experts who offered a number of strategies for cutting down on the supermarket shuffle and also proposed a few suggestions that stores (and customers) could implement to make the process run more smoothly for everyone involved.

One major supermarket chain, Kroger, has already reported great success implementing it’s “QUE Vision,” an electronic notification board that lets shoppers know which lanes are open and which occupied ones are moving quickly. They say the system has cut the average wait time down dramatically, from more than 3 minutes to around 30 seconds.

But if you don’t have a Kroger store nearby with QUE Vision, can’t afford a home delivery grocery service, or simply prefer to shop elsewhere, here are the highlights from that helpful New York Times investigation:

Get Behind A Person With A Full Cart

Wait, what? Chief Desmos academic analyst Dan Meyer tells the paper that it takes an average of 41 seconds to process each person. Getting through the actual items is the easy part. In other words, it will take less time to stand behind 1-2 full carts than 5-6 baskets with less items. “Every person requires a fixed amount of time to say hello, pay, say goodbye and clear out of the lane,” Mayer said.

Choose An Aisle On The Left

Left-handed people have a secret advantage. Most people are right handed and tend to pick aisles in that direction. So, next time consider making the “right” move by changing lanes.

Pick A Female Cashier

Well, this is either incredibly stereotypical or a testament to the superior skills of women everywhere but one expert says on average, women just tend to get customers in and out of the line more quickly than their male counterparts. “This may seem sexist, but I prefer female cashiers,” said Robert Samuel, whose company Same Ole Line Dudes gets paid to wait in lines for more fortunate and less patient clients. “In my experience they seem to be the most expedient at register transactions and processing.”

It’s True, Older Customers Tend To Be Slower

Beacon college professor A. J. Marsden says older customers tend to take a bit longer. But before you call us (or Marsden) ageist, we’re going with the explanation that it’s because they’re just so much wiser than their less experienced fellow human travelers.

The Times offers a few more helpful tips, such as avoiding lines where people are buying a bunch of smaller, delicate items like fruits and vegetables and to avoid lines with structural challenges like veering around corners. Read the whole thing and the next time you head off to buy groceries do so with the confidence that you’ll be in and out in no time.

    Reddit user Girlfriendhatesmefor’s three-year-old pitbull, Otis, had recently become overprotective of his wife. So he asked the online community if they knew what might be wrong with the dog.

    “A week or two ago, my wife got some sort of stomach bug,” the Reddit user wrote under the subreddit /r/dogs. “She was really nauseous and ill for about a week. Otis is very in tune with her emotions (we once got in a fight and she was upset, I swear he was staring daggers at me lol) and during this time didn’t even want to leave her to go on walks. We thought it was adorable!”

    His wife soon felt better, butthe dog’s behavior didn’t change.

    Girlfriendhatesmefor began to fear that Otis’ behavior may be an early sign of an aggression issue or an indication that the dog was hurt or sick.

    So he threw a question out to fellow Reddit users: “Has anyone else’s dog suddenly developed attachment/aggression issues? Any and all advice appreciated, even if it’s that we’re being paranoid!”

    The most popular response to his thread was by ZZBC.

    Any chance your wife is pregnant?

    The potential news hit Girlfriendhatesmefor like a ton of bricks. A few days later, Girlfriendhatesmefor posted an update and ZZBC was right!

    “The wifey is pregnant!” the father-to-be wrote. “Otis is still being overprotective but it all makes sense now! Thanks for all the advice and kind words! Sorry for the delayed reply, I didn’t check back until just now!”

    Redditors responded with similar experiences.

    Anecdotal I know but I swear my dog knew I was pregnant before I was. He was super clingy (more than normal) and was always resting his head on my belly.

    So why do dogs get overprotective when someone is pregnant?

    Jeff Werber, PhD, president and chief veterinarian of the Century Veterinary Group in Los Angeles, told Health.com that “dogs can also smell the hormonal changes going on in a woman’s body at that time.” He added the dog may “not understand that this new scent of your skin and breath is caused by a developing baby, but they will know that something is different with you—which might cause them to be more curious or attentive.”

    The big lesson here is to listen to your pets and to ask questions when their behavior abruptly changes. They may be trying to tell you something, and the news may be life-changing.
