MAN STOP ASKING THE SAME QUESTIONS I TOLD YOU WHAT TO DO...DO IT
IF YOU CANT DO THAT BUT WHAT YOU CAN DO IS...PULL ASIDE AND JUST LOOK DEEP IN HER EYES AND TELL HER YOU LIKE HER AND YOU WANT TO TAKE HER OUT..IF SHE REJECTS YOU MOVE ON IT ANT THE END OF THE WORLD
Easier said than done dude.
Just keep going in at the same time daily and talk to her about just every day things, even the price of things but don't stay too long and wait till its quiet after about the 4th time if she smiles and generally looks pleased to see you, well that's a good sign.
A nice, sweet complement is always welcome by a girl. Start with "Nice smile"
