I don't know. I suppose I would if I had just had a big cook up, otherwise I couldn't see the point for one cup, one glass or one plate !! I might use it for all the pots and pans after dinner. I would need them all the next night, so couldn't leave them in the dishwasher until enough had accumulated. I use them every night !!! I would like to think I wasn't that lazy, but I don't know until I am in that situation. It doesn't take me ling to do the dishes, it's just the pots I don't like. I would think it would be waste of water for just a few items, but maybe I will grow lazy as I get older . The only reason that I would ever be alone is if my husband died before me.
Yes. Our dishwasher broke down and we went without for 6 months until we finally got around to replacing it. It was a real punishment having to hand wash everything (and there's only two of us). Life is to short to spend that time at the kitchen sink BUT most importantly what I did find was that our water consumption and energy bills actually rose in that 6 month period whereas since the new dishwasher went in, those increases have actually abated to what they used to be.
