WHY ARE DISHWASHERS SO INCREDIBLY DIFFICULT TO FILL?

I mean, all that opening the door and putting dirty dishes inside - wouldn't you think the designers could come up with something a bit easier and more 'user friendly'?
Clearly I personally have mastered the art of filling the wretched thing, probably thanks to decades of practice and I have even managed the equally difficult task of EMPTYING it as well, though obviously this has the added chore of having to locate the proper places for all of the contents and this can be extremely hard.
Should dishwashers come with a health warning? It could say something like :WARNING LOADING THIS DISHWASHER MAY DAMAGE YOUR HEALTH/CAUSE INCURABLE STRESS/KILL...
OH, HANG ON A MINUTE...
...MAYBE, JUST MAYBE, IT'S NOT ACTUALLY THAT DIFFICULT AFTER ALL.
Perhaps it's just MY HUSBAND who finds it thus. Possibly he is slightly retarded in the dishwasher loading department and that is why he NEVER manages to actually put anything into it. Even a teaspoon after he's made a drink, is left on the worktop instead of placed in the machine. Plates are left immediately above the door to the machine rather than actually placed within it. Clearly this is a case of dishwasher phobia and I should thank my lucky stars that it's not an affliction from which I suffer.
