We ended up calling my brother who just happened to be at the grocery store that morning & asked him to grab a cake for us. My brother works at the same office as I do & he had waited to grab anything until that morning. He bought some fresh cookies (yummy brownie cookies), he did not want to get them early because he said he would of already been eating them. He doesn't cook very much.
He did a really good job picking out the cake & the message on it was perfect. He got to the office about 10 minutes before our boss got there. She usually comes in about an hour after we do, but she also stays much later than most of us did.
