I questioned the tweet of a DC doughnut place. The "junior staff member" at first said it was just the hashtag they were using, which it wasn't. They must have gone back and re-read their tweet. They ended up deleting their original tweet, coming back with something more appropriate for the day. And inexplicably, they tagged me in the new tweet.

But I then did a search on "happy memorial day" in Twitter and there seemed to be thousands of them from all sorts of different brands. So it seems we are trying to hold back the ocean. Or correct everyone who uses EST when they mean EDT.
