Standing in line for hours (with nothing to show for, be it a plush animal, a new TV or whatnot) can drive anyone insane, especially someone who was unstable and egoistic from the beginning.
I remember buying the last item of a certain merchandise (was an item of limited edition and sought after), and the fellow who arrived to the cashier after me almost broke out in tears when the clerk told him that the last one was already purchased.
Sometimes they take it well, other times they can get a mental breakdown or even become aggressive.
I know i would have been frustrated after waiting in line for hours in Hotel Mirage and found out that the fellow right before me got the final treatment for the day at the Ice Machine.
Then again, it would also motivate me to stand in line earlier the next day in my pursuit of the Blessing by the Ice Machine.
