I'm pretty sure you can quit in anyway you want depending on how much you need a reference from that job. Heck, we had a guy at Walmart pick up the intercom and page the entire store to let the managers know he quit.

Dude at one of my old jobs (A burger place at an amusement park) spit in the burger our boss had ordered right in front of him and told him he quit.

That guy is my hero.
