Most people are right-handed, right hand is handy.
However, most small/medium refrigerator doors swing counter-clockwise by default. This forces you to move/arrange heavy things with your left hand.
Given that the majority of the population is right-handed, this makes things so inconvenient.
Even if you can change the rotation of the door on some large & expensive refrigerators, their factory setting are still default to counter-clockwise.
So why do refrigerator manufacturers prefer doors that swing counter-clockwise by default?
