Since I do day game, when a girl asks me to buy her a soda I usually ask her why. I'll say, I don't even know you yet. She'll introduce herself and slyly say, "Now that you know my name, can you buy me a soda?"
I'll say, "Nah. I don't feel like buying you one." Then I'll look around like she doesn't exists.
After 2 or 3 days, I'll get her some fresh milk and a can of Pringles when I see her around. She'll jump up and down with glee like a 7-year old kid.
It's a compliance test alright. But I look at it in a different angle. I do it for social proof and the emotional roller coaster ride. Because of this, I get invited to a lot of weddings, birthday parties, baptismals, and other get togethers.
Btw, I've noticed in my day game that some random stranger chick will do this after I catch her looking and giggling with her friends. I then buy some refreshments and go near the chick while eating my snacks pretending that I didn't see her. This way the chick opens me instead of me opening her. But you'll have to go to a regular venue that chicks frequent for this to work. I do this at a mall near two universities.
