I did this when the first palm pre came out and for a few iphones. Came home from the pub and offered the homeless guy blocking the door to my apartment while sleeping money to sleep in front of the cell store instead. Woke up, walked to the store, gave the guy cash and breakfast and sat down at the front of the line. People behind me though it was genius.
Several people thought it was uncouth. Don't see why. Guy got paid and I woke him up earlier than usual so he got into the shelter line super early. Win Win.
