So maybe it the same pizza could come from multiple providers but they break it up into slices and attach a pizza-correlation-id to each slice so an entire pizza can be assembled at the point of delivery.
And a table of pre-sliced pizza would be less prone to philosophers starving while deadlocked on acquiring utensils.
What if two philosophers grab the same slice and won't let go?
One eats the pizza first, then the other eats it, problem solved!
That just serializes the problem, maybe the philosophers could just atomically take a slice, but what if its half pinapple and naturally no one likes pinapple and there arent enough slices?
