You're not one for sloppiness. Sure, you're a relaxed, easygoing person, but that doesn't mean you suffer fools gladly or suffer foolishness gladly, especially when it comes to your work. You want things a certain way, and as soon as you make this clear to the people you work with, the better it will be for everybody. Communicate well and lead by example, and sloppiness will be a thing of the past.
