I have recently returned to TS3 and am looking for this mod I think I had at one point in the (distant) past. My memory is not what it used to be however, so perhaps I am confusing it with another game; I am uncertain.
Anyway, the mod worked as follows (afair). You could set 3 mealtimes a day (breakfast, lunch & dinner), and at those times a random meal would be placed in the fridge and all sims on the lot would be pushed to get a serving. Anyone know where I can find it?
