While unintentionally, a person can forget something under their shopping cart or forget to place something on the conveyor belt or maybe walk out of a restaurant without paying, that is not the same thing as walking out of an Apple store with a hard drive under your arm. But I do agree that strange things can and often do happen.
OP was at the Apple store for a genius bar (basically tech support and not there to purchase something) and then carries a hard drive (an expensive item) out of the store under their arm, gets into their car and drives home not realizing the hard drive is under their arm and was not paid for. That would be a strange thing to happen. I would think it's kinda hard to drive home with a box tucked under your arm.![]()
