I have a very, very convenient Walmart including a pharmacy so I do go in from time to time especially for standardized purchases. But I don't really like it. And I poked my head into an adjacent Aldi once and retreated. Otherwise not really worth the headache.

I shop at Walmart and Costco. The customers at the Costco appear much better off, but they seem much more arrogant and inconsiderate. They leave carts in the middle of the aisle, talk on phones with their families blocking the way, and so forth. Same behavior in the parking lots. Maybe it's because Costco is always packed. The shoppers at the Walmart definitely look less well off. They are much more respectful and considerate of others. I like shopping at the Walmart more.
