An Empty Food Dish

Dave prefers to be able to feed himself freely. Though he is nostalgic for his wild younger days on the mean streets of Iowa, he does not miss having to track down each meal. You can imagine Dave's heightened concern during the times when his food bowls are devoid of food. They might be empty because it is not meal time, or because they are being cleaned, but whatever the reason, Dave is uncomfortable if they are empty. 

This is a good example of a DAFECON 3 situation.
