Joined this forum today as to share this specific story. Take heed, enjoy, and try it yourself.
Last year, Christmas Eve, I went last minute gift shopping at the mall. I was shopping for my younger sister, so being from Buffalo, New York, naturally I was confined to Hollister and Victoria's Secret (Sweatpants, not lingerie) to buy clothes and giftcards, etc. The interesting thing about these two stores and this unique time of year are as follows: the stores are stocked with cute girls, these girls are trained to be flirty and open. In Hollister, a cute 20 year old blonde caught my eye. I must have caught her's as well, because she made a point of sticking around once I said I didn't need help. After a moment, I gave her the old nod and she walked over again. I told her I needed help shopping for my sister. This brought up a whole conversation- what does she like? What sort of things is she interested in? I played this to my advantage and found out a little about her in the process. She went to Binghamton U, which conveniently was where my best friend went to school. I got her number, fooled around with her while she was on winter break, and set it up so that I had a booty call in Binghamton. Now, every time I visit Binghamton, I have a fall back.
TLDR - Cute girls who work at the mall will help you Christmas shop and are easy to number close. If nothing else, it will help hone your game.
