I love trying out different fun ways to get people to really think about the survey, and thought if anyone had any really well-received lines they were proud of, they could share here. I'll start:

(To a cute girl and her friend who were buying games for one of their younger siblings and as part of the transaction signed up for a PURP): "And if you have some extra time, you can fill out a quick survey and let Gamestop know how good their employees are at getting girls' numbers, I'm sure they'd be thrilled to hear it"

(To a guy buying a ps4, after joking about system updates): "So while you're waiting for your system to update, you can make dinner, watch a movie, and maybe fill out a quick survey for a chance to win $100 in Gamestop gift cards"
