Be careful about switching between the Android and iOS...I did this in order to Rescue my food, as it is way cheaper on Android. The next day, in Restaurant Story, on my iPad mini, the Gem Machine was MIA! I finally had to delete the game and reinstall it in order to get the Gem Machine to show again. Tech Support kept telling me...It's in your store right next to the Frozen Lakes Machine...but I couldn't access it!
