Please expand - my experience of dishwashers (at work, mainly) is that they are so regularly unthorough, you actually check every item of kitchenware for cleanliness, before using it again.
You don't do the same, for hand-washed items.
Our Bosch DW is a boon. The one we had previous was a wee bit temperamental, but that was because you needed a degree in DW loading to get the best out of it.
The Bosch fella is the dogs. It still requires thought when loading but cleans like nowt else. As long as you load them correctly then hand washing does not come anywhere near as close to the sterile squeaky clean you get from a (correctly loaded) DW.
People who have more important things to do own and use a DW. We have children. We have jobs. We have hobbies as do our children.
You crack on and wash your dishes and whilst you are at it pop down to the local river with your dirty washing, mangle and soap board on your horse and cart eh.
