The theory is that we all are conditioned to respond to direct commands as children and still do (even to embedded commands hidden in language that means something different, even the opposite). without ever giving the embedded commands any conscious thought.
Infomercials use it big time " If you (Buy within the next hour!) you (Get a Free Second Set) for an additional shipping and handling charge only. If you (Act Now!) we will send you our thank you gift, a box of four stainless steel steak knives. if you (Call Now!) etc.
Some embedded commands for someone getting picked up in a club:
"Do (You want me!) to tell you which actress/actor you look like?
(Tonight you should come!) for a walk on the beach with me after this. Are you getting sleepy already? I don't know how (You are going to sleep with me!) yelling over the music in here. Do (You want us to get out of here!) ? Okay but you can't (Let me take you home now!) without dancing one last song. This place was so much fun tonight. (You should make me come with you) again next weekend.
