It's not as big of a thing here as it was when I lived in the Midwest and in Florida. I've lived in the Seattle area 17 years and while we do have some 24-hour locations for things, they tend to be more spread out than what I got used to living in smaller metropolitan areas. For a long time, the big chains just didn't have as big of a presence here. When I moved here, there were only two Walmarts in the Seattle area; CVS has only been in the area less than 5 years. Costco's the big warehouse chain (not Sam's Club) and they're known nationally for paying people fair wages. A lot of local chains simply do better on this side of the mountains (as we say here) from Eastern Washington and parts farther east. The tradeoff has been not as many 24-hour locations for things; I once drove 20 miles to find the nearest 24-hour pharmacy. We do have Kroger here, represented by QFC (grocery) and Fred Meyer (little bit of everything, more on the home goods/clothing side than grocery). But yeah - speaking as someone who grew up in the Missouri/Illinois/Indiana area and then moved to Florida before moving here, it still feels surreal to know that if I wanted something at midnight, I'd have to go out of my way to get it.
