I upvoted you because what you're saying is true now, but it wasn't back then. Both Costco and Sam's Club 25 years ago were truly "warehouse" stores. They had no heat. No air conditioning. They weren't brightly lit as they are today. Nowadays, they both have decent-to-above-average well-lit interiors that are designed to be essentially middle-class (in the case of Sam's) to upper middle-class (in the case of Costco) stores that are just "really big". They were little more than distribution centers with printed price tags on items back in the mid-90s. A lot has changed, about both chains, since then.
