The best thing to do is to not be THAT GUY with the Costa Del Mars hanging from the rearview mirror, or the duck calls hanging from the mirror, and the worst is THAT GUY that keeps his Costas around his neck when he goes into a bar, store, etc.. and its ten o'clock PM!! The sun ain't coming out any time soon, you will be fine, the lights in the bar, store, etc. are not that bright, you will be just fine
