F$%^ that. I'd keep the money.
Rich lady walks up all prissy like "Hehe. Watch me go use my money power to go buy up all the phones these people in line are wanting, and go make MILLIONS on ebay!"
Then she pays the kid in the front $800 for his spot claiming that $800 is chump change considering all the money she's about to make.
Then BAM! No dice! She can only buy one $600 iphone!
So not only does she end up spending $1400 on a $600 iPhone, but the kid who gave up his place in line for $800 STILL got the phone he was wanting anyway, cause he had two friends with him, and combined they only wanted 3 anyway!
So rich snob lady spends $1400 on an iPhone, and the dude she thought she duped got an iPhone for free PLUS $200 dollars!
CLASSIC!
