And that’s great if that’s what you want. OP was just saying that free, internal lunch promotes team bonding for those who do desire it.
Miracles do happen.
The upstream comment even said free lunch "promoted" camaraderie, not "is the only way it can happen."
Rationally, there’s no inherent reason that free lunches promote “bonding”, and no inherent reason that teams that go out to lunch won’t bond. It’s just cargo culting and post hoc rationalization for people liking free food.
Intellectual rigor is alive and well on HN.
