The fast food store has 8 processors (cashiers/cooks). While the concurrent burgers store might have had only 2 (one cashier and one cook).

But still, the final experience is not the best. 😞

This would be the parallel equivalent story for burgers. 🍔

For a more "real life" example of this, imagine a bank.

## Why Pull Requests?

Pull Requests (PRs) drive quality in MinIO’s codebase by:
- Enabling peer review without pair programming.
- Documenting changes for future reference.
- Ensuring commits tell a clear story of development.

**A poor commit lasts forever, even if code is refactored.**

## Crafting a Quality PR

A strong MinIO PR:
- Delivers a complete, valuable change (feature, bug fix, or improvement).

  Please see [the KEP](https://github.com/kubernetes/enhancements/tree/master/keps/sig-storage/1710-selinux-relabeling#story-3-cluster-upgrade) how we expect to warn users before any SELinux behavior changes and how they can opt-out before. Note that this field and feature gate is useful only with clusters that run with SELinux enabled. No action is required on clusters...
