Recycling confusion

Today I was at a meeting for work. They had muffins, orange juice, and coffee. I enjoyed my blueberry muffin and a glass of orange juice, and then at the break, I went to throw away my garbage. I was confronted with five containers with instructions and slots with different shapes and cut outs:

1.  Glass - square slot

2.  Bottles and cans - circular slot

3.  Paper and cardboard - diagonal rectangular slot

4.  Plates and napkins - large square opening

5.  One big garbage can with a black trash bag and no top

So where do you think I put my paper napkin, wax paper muffin wrapper, plastic cup, and heavy paper/ cardboard like plate?

In the container that was easiest.
