Costco has a right to have a policy that requires a mask. The man HAD a right to shop somewhere else. This man is a fool
If Costco did not require the masks, I think they would see their sales volume plummet. Sure, cool FReepers like us may eschew the masks, but there are a lot of snowflakes out there who won't shop without the phony safeguard of the masks.
While I was shopping there this past Saturday, I glimpsed a hardcover book in the basket of a young hispanic woman. Out of curiosity, I took a look at the cover. It was the new book by Obama. Anybody doubt where that young woman stands on the subject of masks?
