It was always the plan to split the costs. Yes, it is a student house and the custom of the house, since we're on limited funds, is that someone buys the food then we split the costs evenly. We've done it before with all of our shared meals, and that was what I was trying to get at with my post. I didn't do a 'restaurant' and invite people over and demanded that they pay. I asked them to split costs of the food itself and nothing else, just like we had always done. And I did ask if people could bring things, but I ended up having to get most of everything except for one side. If they brought something, someone did actually bring vegetables, it was ok. Again, just like we had done before with other shared meals.
