So I was at work. I'm a barista at Starbucks.. I see this woman frequently at another Starbucks I go to close to where I live. So I was making her drink and I say to her..."I see you frequently at the other Starbucks", then I went to very brief small talk while making her drink, (like a couple of sentences). At the end of it, I give her the drink and say goodbye.... Then she says, " come over next time and say hi". Does this mean she's interested? Is this a neon sign that says she's interested....I talk to other attractive girls I see there, but she's like an HB10 and I didn't think she was available.....
