We got one on Thursday last at the Storybook Princess Dining in Epcot (Norway). It was dd's birthday and I had ordered her a cake, which by the way was beautiful! There was FAR too much to eat in it for just the 3 of us, so we sent the cake around to all the other princesses sitting around us.
At the end of the meal, the manager approached my dh and gave him the 2 pins and explained that they were only given to guests who "give exemplary service to other guests". He said that they were stunned by how generous we were with the cake - what's a birthday if you can't share, right? It was a really nice gesture and something that we will treasure!
