Due to Raccoon's food allergies, we never eat at McDonald's. But we happened to be near the one with the largest play area yesterday. So we stopped in, to the immense joy of our kids. As playtime was winding down, the hostess came over and asked us if we'd like a kitchen tour. Yes!
After suiting up, we went behind the counter. My favorite thing was the soda machine (picture below), and at the end, free sodas. The kids liked washing their hands and pulling on the rinse hose above a large sink out back. The King was impressed by all the cleanliness measures and considered it a tour about the danger of germs.
Overall, a win-win for everyone, and the bonus of an unexpected field trip.
