I joked that I was a half pizza team on my own. The commute had me riding 25 miles per day on bike, I don't eat breakfast and only a light dinner -> lunch was easily 4 slices of pizza.

Thus two pizzas is 6 to 8. 2 slices is usually assumed to be the serving size. 20 people is not even one slice per person
