I put a "cart" of things in my fridge

Ok so I work at Target and I noticed the other day that this cart was really sturdy and high quality so one of my coworkers, who was also an employee of the cart, decided to take it home and turn it into a fridge. <br>He put all the shelves in the fridge and all of his food and stuff in it. <br>It's working really well I'm just confused. <br><br>Edit: it's a microwave cart, he put it inside his normal fridge and put all his food and stuff in it.
