Halloween Delivery

So I read a story on FB. A girl had her baby on Halloween, she had it early. Her doctor was called in, and he came in dressed up as the joker, he was heading to a Halloween party. Would you be offended, or would it bug you as it was actually Halloween? I would rather look at him and be able to laugh and have a great story. But I called him staff and holy crap someone freaked out as he didn't go to work that way for the day, he was called in! Technically he's staff while he's at the hospital because he is an on call doc, which was beside the point of what the story was actually about!
