To make a long story short, there is someone in my household that I do not trust. I would like to find some kind of food storage containers that I could place in my refrigerator that is lockable. Does this exist? If so, can somebody point me to some products I could check. Also any ideas on alternative products I could use that will achieve the same goal? All ideas, suggestions, opinions, etc. are welcomed. I don't want to fork out $50+ on compact refrigerators. TIA
