One year at Christmas, I had a boss who was extremely, well, CHEAP!! It was so bad that our director finally told him that he had to do something for us at Christmas. He could arrange for us to have lunch together where we paid for our own lunch. Or, he could buy us each a Christmas card.
But, he chose not to do either. Instead, a half hour before quitting time on Christmas Eve, he walked around the office, shook our hands and wished us all a Merry Christmas. He then announced that he was leaving early but still expected us to work until our quitting time.
I guess letting the rest of us leave a half hour early on Christmas Eve was more than his neurotic Catholic psyche could handle.
