Quitting a job without notice.?

I just started working at a restaurant about a month ago. I absolutely hate the job/hours/management and I would prefer to just quit/stop showing up now, without giving them a 2 weeks notice. Is there anyway I could get in trouble for this? It's at-will employment so I highly doubt it. I've already recieved one paycheck and the only drawback of not showing up anymore is...I will have to come back to pickup my last paycheck. I know not showing up anymore is not the best way to quit, but I'm 17 and I would never even put this job on a future resume so it doesn't matter to me. I'm just wondering how to avoid awkwardness when picking up my last paycheck?
