Neighbor probably took his/her's kids gift card and gave it to sweeper.
After psychoanalyzing the situation, i believe he gave it to Kenny (sweep) b/c he is always so fukking dazed and fukking out of it because of the blow that he figured an expresso or some juiced up coffee would do him some damn good so he could have the energy to plow his driveway more often..... he figures the more caffeine he feeds Kenny, the more his driveway is done.... hence, next time you may get a $10 Starbucks gift card, etc.
Neighbor is playing mind games, we'll see if Kenny is smart enough to cut the deeds off now or continue to feed into his demented charade.
