Thanks

Go for it! Don't let anything get to you, YOU WILL GO UP TO THIS CUTE GIRL AND YOU WILL TALK TO HER.
Be funny don't hesitate, but if you do it;s actually really cute seeing a guy get shy but don't sweat or anything thats a nono!
Okay so go up to her give her your cutest sexy smile and be like "Hey so hows work going..?"
Make something up!
if things go good and she giggled slightly then wait for a second till she looks at you with her cutest smile and make sure you stare back at her smiling and this is the perfect time to say
"How about we grab lunch (tomorrow/monday whatever day!)"
AND WHEN YOU SAY THIS MAKE SURE YOU SOUND VERY CONFIDENT!
:)
YOU CAN DO THIS JUST TALK TO HER :)
goodluck!
