There are ten Canadians in the room. It's been ten minutes since this situation

What? No! The order goes "Anyone want this?" *chorus of no's* "Seems a shame to throw it away" *many sideways glasses* "I'll share it". Then the First Speaker gets a bit less than half, and the other share goes to "I'll share it".

Nah it goes
“Anyone else want this?”
“Go halves?”
And then you go halves with that person. That middle step is just unnecessary
