Perhaps worth noting that this Costco experience is localized. I've experienced it myself in Los Angeles when visiting, and when I lived in the Bay Area. No carts. Takes 10 minutes to get a parking spot, etc. But here in Montana Costco is very chill. The same people have worked there for 25 years and will ask you how your kids are doing. Plenty carts. Plenty parking. There is still the cell phone guy but even he can be defeated with a cheery "my company pays for my service".
