This doesn’t even remotely match any experience I’ve had with Apple or Apple devices in almost 25 years of use.
I’d check back with your “friend” and make sure she was telling you the whole truth.
PS: the serial number of her laptop is printed on the bottom of the case - which should address this very, very strange story implying the Apple staff slipped her a dodgy beat-up old laptop. The number should match her invoice and the box (but I guess your friend doesn’t have an invoice or a box, or probably any other way of identifying her laptop other than ‘stickers’)
