Does she think I'm a creep?

So I just started going to this new plasma place and there are a lot of pretty girls that work there 😍 Well the girl who was doing my vitals when I became new took my pulse and it was like 108 or something. So she said it should be under 100 and I said that she was making me nervous lol This wasn't true but it was just my way of saying "GAH DAMN YOU FINE" without saying it. Now, before I said that, she was really sweet and bubbly but as soon as I said that her tone kinda shifted a little bit. I don't think I noticed it at the time but looking back I can tell it did. Anyway I thought about her all weekend like a lot so much that I think I manipulated destiny in order to be able to sit with her to do my vitals again the next time I went and then at the last second convinced myself she didn't give a shit about me and I didn't even want to sit with her but then imagine my surprise when I end up sitting in her booth 😲 but the worse possible thing happened and she was having a bad and she was very upset about something. I was going to tell her I liked her hair but I just couldn't. I mean her attitude from that first day to the second is really night and day. The weird thing though is that I keep getting sat with her and Everytime now her attitude is horrible. Yesterday I just let another guy go ahead of me so I wouldn't have to sit with her because it honestly kills me lol. And idk what happened like she was so sweet at first!

The only thing I can think of is that maybe she is really young like 18 or so (idk how old she is) and I'm 32 (33 tomorrow actually lol) even though I look young she may have just felt weird that I said what I said idk. I imagine she 18- early 20s people in tell me I look around that age all the time
