On the iPhone 4 launch, I was 7th in line. The store opened at 7am, I was there since 3:30 or 4 am. They guy that camped all night was a hardcore fan and couldn't be bought, however the number 2 dude in line ended up with a free iPhone 4 as the gent that strolled up and pulling out a roll of hundreds and asked to purchase a spot in line as he did not have time to wait but was willing to make it worth someone's while. $600 cash, and the kid went to the back of about 50 or 60 ppl in line.
I don't really have an issue with it myself, it doesn't effect my spot or my time in line, if they buy the spot and the holder leaves, it really doesn't effect me at all. It's always interesting to see what people will take for a spot, that so far is the largest sum of cash I've seen given.
Which btw, happens all the most people just don't see it. I've been with a buddy that more than once has slipped a wad of cash to get into a resturant that has a 45 min wait, in 5 mins. No one bitches because people just don't know it. Cash talks, in every situation.
