Our unit is charged per item for things we use from the dietary dept. We still serve dad a meal at meal times(for now) but to save money we stopped ordering the laboring mom's clear liquid trays at meal times and just let them know we are now better stocked with the liquid diet items in our kitchenette and we can get them what they want throughout the day. Most of the trays from dietary sat because they either weren't hungry at the time, or were just delivering. It also makes for less trays to pass now. So far it seems to work great. :)
