I believe this is why Jeff Bezos has the two pizzas rule [0].
Anecdotally, to this day we get surprised reactions (mostly by investors) when they learn that our massive service [1] was built by 6 engineers. More people requires more synchronizing, which leads to more meetings and results to more time waste.
At my last company two pizzas would be eaten by any two people, myself included.
At my current company, they'd have to order 2 vegetarian, 2 gluten free, 2 plain cheese, 2 pepperoni and then for some reason 1 anchovy pizza that nobody would even touch. And it would take a meeting just to figure out the pizza order for the other meeting. Then another meeting to discuss who needs to go to that meeting.
You nailed it. We have so many diets within our company that there is no way we can go out together and everyone to be happy. Even ordering snack is a torture.
