Please reduce the BBQ attraction

A recent experience has made me question how aggressive the autonomy is. I moved a family of six into the new house and all their needs were about the same. Nothing critical but they were lowest in hunger so I send one to make a family meal and wouldn't you know it, I had to play goalie for five minutes while she finished it. Without fail I had to stop the five others 3 times each from trying to get something to eat (quick meal, cooking, grilling, etc.) and then had to tell the to grab a plate. I know that there is a call to dinner interaction, but you would think if they were so desperate I would not have to use it.
