where is all this food coming from ?

I'm not sure why this is happening, but before Discover University came out, I was building and playtesting a restaurant and it was horrible, because customers would order food and then bring out their own tofu dogs and other foods. I'd have my sim clean up the plates, but they'd still get out more food. All the tables were flooded with homemade food and there was no space to put down their orders. Needless to say, it didn't end well :D But now the magical abundance of food is happening in dorms as well and I'm wondering what the cause is, since it already happened in my restaurant before this expansion pack. I thought it might be another Dine Out bug, but apparently there's more going on.
