If someone pulled a prank on you while you were away for a while, and took your refrigerator door and swapped the hinges and door handle sides, would you even notice?
Would you be confused? Would you be mad? Would you even care?
LOL, I'd never do this, but it seems harmless silly enough...
A lot of fridges are made to go both ways. You have to attach the handle and the hinge when you get it. A lot of fridges will have two plugs on the other side to cover the unused bolt holes
