But when you wash up in a sink you still have to collect everything and put it away? And you wouldn't plunge a plate with scraps into a sink full of water either.
I don't really understand when people go on about the faff of dishwashers, when it's literally exactly the same faff which is required when you wash up except you don't have to actually do the washing part!
Especially so on a thread which is about having two... meaning you don't have to empty it EVER, and filling is no big deal because you do it as you go.
If you are referring to people who just leave their shit piled up on the counter instead of putting it directly into the ready-and-waiting dishwasher though, YANBU that is a pain but it's the people who do this who need to be reeducated.
