Manager kinda fucked me over with this one girl (unintentionally)

So basically, I met this girl today at my new job and we seemed to really hit it off. We eventually got off work at the same time and we were standing by the time clock and she was asking me if I had a locker for my stuff (since I was carrying some of my shit). I told I didn’t, I was thinking about getting one tomorrow then she said she’ll let me use hers. Right when I was about to respond my manager comes up “oh you need a locker?” and I ended up having to stay behind a bit while she left. Manager took a good minute with it too. Not saying if she hadn’t come in we’d be dating or some shit but seeing how fast pace my job is and how hard it is to get to talk to people there i felt a tad bit salty about the situation. It’s my managers job ofc to ensure her employees get situated with the job so I’m not mad at her, it’s just the timing was fucked up.
