So this past weekend my group went sarging at the new forever 21 that opened up at our mall. This is the routine we used:
"could i get your guys opinion on something"
"Im looking for a present for a friend of mine thats a girl. I need a universal gift that most girls would like. what do you think would be good?"
(suggests some items)
"can you show me where those are at?"
at this point they should be leading you around the store showing you a ton of stuff. just playing along is good at first, but you want to transition to normal talking fast unless they might get suspicious. also you have to keep talking, dont let any awkward silence happen. when it did for me i would ask a question i know i would get a fast response to, "what do you think about shoes as a gift?"
some things you can add in are:
"the girl we are shopping for has the same body type and hieghth as you! (point to the most attractive body in the group)"
i could have my wingman come in by saying "have you found anything yet?" and you can also use the wingman throughout the whole thing by just approaching a group all together.
