This is more Walmart behavior.
I became a member of Costcl back in1988. The only store was fairly near where I lived (renton highlands). I saw their membership idea great because it really did keep out the “riff raff”.
I’ve been in that store recently. After living in rural Kentucky for 13 years, it is so international that the last time I was there it took me a while to find a single white person. Frankly, it was fascinating. Seattle has definitely changed. And I definitely feel more at home and “at peace” in a more “homogenous” area.
I suppose it’s just human nature.
Why is it described as being Costco?
