How do I repay an act of kindness? m26 F22 & F23

I was out with a couple of people from uni and got pretty drunk, they ended up leaving me by myself in a club. It got to the point I was delusional drunk. I hadn’t had a drink in two months. These two girls noticed and told me I could chill with them which I was grateful for. One of the girls was really responsible and had a sense of independence about her and made me feel safe, which is weird because I’m used to being that person. I fell a little bit in love with this girls whole vibe. She waited for me to get a taxi before jumping in her own, I’d like to ask this girl out on a date to get to know her more but she struck as someone who isn’t really looking for anything.

I told them I’d repay their kindness and asked where they worked, they both work in a club. I don’t know if I should just send flowers to the club addressed to them or maybe go and thank them in person so they can see am not a drunken Idiot, Or should I just move on and forget about it and just leave it down to drunken antics?

Tldr: got really drunk and friends left me alone, two girls looked after me and I fell in love with one and don’t know how to thank them. Send flowers to the club they work or thank in person.
