Has anyone ever greeted you by saying, Happy Memorial Day" or something similar?

Yesterday, actually. A women at Lowe's thanked me for my service (I always wear my Navy retired cap) and said "Have a good Memorial day.".

Yes, that has happened to me a few times.  Given the reason for Memorial Day, there is nothing "happy" about Memorial Day.  Yet, a grocery chain had "Happy Memorial Day" printed in its advertising.
