Just returned from doing some shopping, among which I discovered:
The scissors I bought were plastic-clipped to the packaging, needing a pair of scissors to release
and
The screwdriver I bought was screwed to its plastic packaging, needing - you guessed it - a screwdriver to release
I wonder how many injuries are caused by people trying to bodge their way into such packaging because they are not already in possession of the very thing they're trying to get at!
