What do I do?

There's this part time job I really want and it's close to my house like an 8 minute walk away at this convenience store but they don't have any online applications or anything (I looked trust me) they just put up a piece of paper on the walls of the shop saying they urgently need a part time worker so I'll probably have to go up to the counter to ask about a job except I'm not the most confident person and that makes me feel nervous but I'll probably do it in the end but seeing as there isn't any formal way of applying should I come with my CV in my bag? I have it online but should I print it? How will this go? Also even though I'm my first year of uni I have never had a job before so will they even want me??? How are you supposed to get experience if all jobs require experience beforehand??? Also they said they need someone urgently so maybe they'll take me?
