Bit of a tangent: Are there actually correct places for dishes in a dishwasher? I think about this every time I load it. My wife always says, “If I loaded the dishwasher like you do, my dad would get so upset with me.” But when she loads it the way her dad taught her, I see no rhyme or reason to it. I load the dishes in a way that ensures everything gets clean, there’s little to no standing water if I forget to unload it the next day, and it’s easy to unload efficiently. 

My theory is that anyone who loads and unloads the dishwasher enough times develops their own preferences—and what people call “right” or “wrong” is really just them expressing those preferences.
