Not so much a hatred - more of a "what's the point?". I mean, I can see the point of a washing machine. Doing the laundry used to take all day long, but with washing machines it can be taken care of in a couple of hours. Dishwashers, though ......
For starters, if the dishes are particularly soiled, you need to rinse them down first of all. Then you have to load them into the dishwasher - load up a ridiculously expensive dishwasher tablet and then two hours later you have to unload it all. It takes about two and a half hours in total - half an hour of which is manual labour and yet you could have done the washing up in 15 minutes!
Really - what is the point of a "labour saving" device that requires more labour than the task it is supposed to replace? Not only that, you can not out anything too large in there or things like roasting trays (they rust) so you end up having to wash those up anyway. So not only does it not save you any time, you end up still having to do the job it is supposed to do anyway.
Mrs Stan loves the dishwasher, though. It must be a woman, thing.
