If only there were some temporary method to get dishes clean without a dishwasher. Because it is temporary, it would be acceptable if the method required more human labor than the dishwasher method.
If only a person were to do some math and realize that spending four hours installing a dishwasher is less time than doing dishes by hand for a month. (and dealing with 50% odds of getting a terrible install by grumpy people who ding up stuff in your kitchen)
I mean I could but time is money. Time spent washing dishes could be better spent installing the dishwasher.
