it is possible, you just got to make small fluff talk with her as she is scanning your items and putting them away. so the next time you go to the store she will remember you. it happen to me today at Mcdonald's. i was there with my uncle just to get some thing to eat and the place was busy. so i just made some fluff talk with her as we waited for our order. by the end she was telling me that i made her day and i should work there with her. so later on the same day i came back to ask for a application and she help me fill it out, we fluff talk and kino for a good while. i could of K-close her but she was under 18
and i don't want to do that. but it just show that anything is possible if you at least try.
