@cstross @TallSimon @stevendbrewer Interesting! While I knew both Trader Joe's and Spirit Halloween were US only, I assumed their defining attributes were world-known, if only for the memes which have escaped the containment of US culture.
Trader Joe's: Smaller scaled grocery store (compared to US supermarkets), almost all white label store brands, "hipster value" fanbase. Owned by one of the Aldi's (can't remember which), actually.
Spirit Halloween: Pop-up seasonal retailer, tends to rent abandoned retail space, does the absolute minimum to make the space usable, and sells costumes and stuff for a month or so before re-abandoning it.
Oh, and K-Mart: Department store chain, mostly went out of business decades ago.
