The pints are made of cardboard. A pocket knife would make short work of the bottom of the pint.
That’s what I thought too. They need them behind locked doors and have the customer pay first. Just like at gas stations.
I was just going to say that. Personally, I would use a carpet knife which is sharper and more precise. Are the demographics in question really unable to figure this out? Or they think knives are only for stabbing?
