Dating

What's a good way to build up courage and a good way to ask her out?

Hey, so there's this lady at work I've thought about asking out. Before I get anyone who says I shouldn't date a co-worker, we both work at a grocery store, but I work front-end and she works in grocery. We talk here and there, and she's always really nice and friendly to me, but I really don't know very much about her. I don't know much about her hobbies, life outside of work, I don't even know if she has a boyfriend. I've never seen a wedding ring or any rings on her fingers, but of course, that doesn't mean she's not married. I really enjoy talking to her and I'd love to get to know her some more. I think I have a solid chance at it if she's either not dating/married to anyone. Honestly, it's been a while since I've asked someone out that wasn't on a dating app, so it's not like I'm experienced with this. And I did decide a little while ago that I would love to give it a shot, but a part of me is still kind of fearing rejection and judgement. I know, you'd probably say "Worst she could do is say no" or so. I don't disagree with that, but still. And what would be a good way to approach her about this?
