I think the cases described are simply outliers of employees having reached their peak at what they do (wink-wink my previous post in this thread), and/or a genuine brain freeze on the employee's side at that very moment.
In the grand scheme of things, Costco continues to be leaps and bounds ahead of other equivalents, simply because of the retention rate they have for their employees that gives them the chance to actually learn stuff. Anyone complaining about Costco service should end the day with a visit to the local Lowes or Home Depot in the same area, the same day. Mission: find relevant information on ANYTHING.
Very simply, in my area, needing 10 items at the big box hardware stores, with five of these items requiring help or advice, is a two hours experience. It has happened to me. One of the items was "What are these thingies that you pull to turn lights on and off?". I didn't know what it was called. Turned out it's called a "pull chain". Duh. 25 minutes diagonally criss-crossing that HD, sent on different missions checking things that could be but were not. Each one included several minutes of running and screaming to actually get anyone to talk to.
Amazingly enough, my debit card also got hacked in that same HD that same day.
Three weeks ago I spent 25 minutes at Lowes searching for "paint to seal my foundation with". Literally - that's what my guy said. "Go to the hardware store and get that black thick paint thingie that looks like asphalt"
Twenty five minutes of my life spent with people who had no clue, speculated on Drylock (yeah but there were three million of them), looking for cement, concrete and everything in between.
Eventually I called it a day and asked Ai, and it turned out it's called - drumroll "FOUNDATION SEALER". Henry's. Black stuff that looks like liquid asphalt. That SEALS. Seals what ? FOUNDATIONS !!!
Go to your local Costco. Look at the employee's tags. They list the year of hiring. Do the average of how long they've been working there.
PS: Shoutout to the REAL hardware store in my area, Ring's End, which I'm blessed to have (apparently they are NE only). Will only say that they have Festool on their shelves. Nuff said.
I find my local ACE Hardware a refreshing shopping experience! My local ACE is small enough to care about customers and big enough to always have what I need.
In my Resort area I can always count on the fact that my local ACE employee is perhaps a retired older person with years of hardware experience and he grew up with a strong work ethic and is simply a nice person willing to help a customer!
Its NOT Rocket Science as My local Chick-Fil-A gets it! I am always greeted with a smile and a I get a "My Pleasure" as the response I when I say thank you!
Ever notice the confused look you get if you say Thank You to a Walmart employee?
I have fun with it, EVERY checkout be it Walmart, Lowe's, to McDonalds I always ask the cashier so "How is your day"? I then shut up, look them in the eye and enjoy the response.
I find the response I get tells me EVERYTHING about the "Culture" of the Company from the owner to the manager to the cashier themself.
I may get a nice "As long as I'm breathing I'm doing GREAT and Blessed" with a smile or I may get a grumpy " I'll be better in 30 min when my shift ends"...
But even that grumpy one I try to spread some cheer or a simple God Bless... But I find sewer flows down hill as if you have a grumpy cashier you got a grumpy manager / owner.
In General ( not always ) I know what response / customer experience I will get depending on the name of the Business over the front door.
As bad business "culture" brings more "bad business culture".
I could write a book with the comments I have heard over the years just walking the isles at Walmart from employees talking to each other. Constant complaining for all to hear with things like "IF She expects me to do this, she has another thing coming" to she did this or that to my schedule, I seldom EVER see a employee smile or say anything nice, from what I see is Walmart is one BIG Grumpy place to work but it flows from the top down!
Toxic culture IS Toxic and spreads...
At least with Amazon you don't hear how bad the employee has it when simply buying shampoo.
