Wow, same thing happened to me!
So I'm chilling in Chipotle last night, as I do, eating my burrito bowl. A cute HB7-8 walks in for a burrito. I'll guess she is 20. I'm not out gaming yet, but I figure this will be a good warmup. I finish my burrito and toss the bowl. By this time she's on her way out. To-go burritos are the devil.
I walk out the door right behind her, tap her on the shoulder.
"Excuse me..."
"Oh, sorry."
"Ha no, I just had to come talk to you before you left. I'm 8s9s10s."
"Oh. Hi, I'm Kate."
"Where are you headed in such a hurry, Kate?"
"I'm actually headed over to Starbucks" (across the street and down half a block).
"Oh, hey, me too, I need some green tea. [this is actually true] I'll walk with you."
So we walk down, I ask her where she lives, what she's doing after her frappucino (a party), etc. She is returning questions. She is pretty shy, but that's to be expected, I'm a casnova, and she doesn't look like the type who is used to talking to boys.
We get to Starbucks, we order, and I tell the guy we're separate (because bump dat, I ain't paying for her $5 coffee). She says she need to get to this party, so I go to hand her my phone, when I realize I left it at Chipotle. So I have her put my number in hers and scramble back over there. I am back in two minutes to show her I found it.
Here's where shit gets real. The guy behind the counter says she said I grabbed her out of Chipotle and dragged her over here. I'm making her uncomfortable and I need to leave. I do not believe this because I am a super friendly guy, so I start bantering back with the guy, who I recognize and have bantered with before, in a friendly way. His next move is "you need to leave or we are calling the police." He picks up the phone and dials. She asked them to call the cops"Whoa, guys, what? Ok, look, Jesus, I am leaving."
I go out and finish my tea outside. A cop pulls up. I ask if Starbucks called him. Turns out yes, he's there for me. I explain what happened and he's clearly on my side, but asks for my name, address, etc. Two more cops show up. Oh boy.
I go up the street and wait fifteen minutes or so. I go back to starbucks and talk to the guy.
"Dude...do I look like I was trying to grope her? I was just talking. I didn't even try to buy her coffee. Come on." *To be clear here, not apologetic, just incredulous.
"Yeah man, I don't know. I've seen you around, you're ok. But just be more careful."
"More careful how? Never talk to anyone?"
"I don't know. Maybe."
So there you have it. The worst thing that can happen when you approach a girl. I used the story the rest of the night though and it went really well. The worst that can happen is you get an awesome story.
