Biggest reason I don't go grocery shopping at Walmart. Doing a full cart through a tiny self-checkout area is a PITA.
French ones still run in criminal mode.
I get really miffed at how our system of economics seems set up to destroy rather than promote the common good.
Painful for small items or when you have a helper.
Also recently I started using what I guess is the Swiss (Coop) equivalent of Scan and Go: I scan with my phone in the aisles, but stuff in my bag directly in the aisles as well, and when I leave the list of items I've taken is transmitted to a classic self checkout machine and I just have to pay. I wish I could avoid the machine entirely and pay from my phone, I assume it will exist one day.
The scanning area will have it owns weight sensor for unweighed fruits and vegetables. This scale is usually calibrated/verified by a government body because it relates to pricing. In Europe, it's common to bag and weigh your produce in the produce section, but in N. America, it's integrated with the checkout process.
I live near a Walmart "flagship" store and they are/were testing out a system where you scan items are you pick them and then can bag them in your cart, with a special aisle for exit. I suspect the cart also goes over a scale and they determine if it matches correctly.
Checkout-as-you-go instead of filling your cart and checking out at the end.
More then a few carts got left half unloaded.
Related, Publix is one of the South's top selling points. It's easily the best grocery store I've used. Up until I moved to Florida and experienced Publix, all grocery stores felt more or less the same.
Safeway has managed to piss off every singe one of their employees.
My local Safeway couldn't find help for years.
Since the epidemic, that is changing. They are hiring people who don't care much about conditions, or pay, and I know I'm suspose to say that's great.
Those people will get tired of being treated terribly in the future though.
I bet Safeway is lobbying the state right now to allow booze sales through self-checkout. The only people I see in line waiting five deep is liquor sales.
Plus with contactless payment my shopping is an essentially frictionless walk through the store building.
