Two things:
- Did your friends know you were going to have a bunch of food and they were expected to eat it?
- Was your party at a time that people normally eat?
I find that if it’s too early/late or if you didn’t tell them what was expected, your results are suboptimal. Could just be your friends, though.
That’s a long-ass party. I would have eaten all of your cheese in that timeframe. All of it. Do you have anymore?
