I was walking out of the gym going on my way to my place, and while walking on a crowded street I spot two hot girls. I pass by looking at one of them and she catches my eye contact, looks (I AFC like a boss) and laughs. She asks me "Hey, you gonna go dancing tonight?"

Me: "Nah, I have to train." (I was carrying a big backpack)

Her: "Awwh come on!"

Me: "No, really, I must train".

Her: "Oh well, if you change your mind, here's my number". She gave me a contact card for a club and wrote her name and number on the back.

Then she said "Oh, I was looking at the mirror" (there was a glass behind me), to which I replied "Yeah, and I was looking at the cars".

It confuses me because I thought she was just working and doing publicity for the club, and being flirty because that's her job. But my brother told me "They never put their number all they have to put is their name. She gave you her number", and then he told me "You call her tomorrow".

I feel really insecure because I was totally clueless on what to do when she opened me and I was completely beta. Seddit, what is your opinion, call her or no?
