We asked one og the roaming cm's in a blue shirt with a large bag. he had just given buttons to some family for thier first visit. it was my wife's bithday a few weeks prior to us going. we told him, and he told us he was out of buttons, but the female cm on the other side of the park had one. He called over to her. He asked us where we were headed, we told him Small world. We were told she would meet us there. We were greeted by three of these roaming cm's and they gave her the button and sung happy birthday to her at the exit to Small World. the rest of the day, those three went out of thier way to pop into lines, resturaunts, and anywhere they had seen us just to yell Happy Birthday!! ......and people wonder why we go back to disney year after year. They also gave the rest of us various buttons too.
