It also works well for loose leaf tea, but I just use mine for coffee.
I have two - a full-sized one and a mini one.
That's how MrsT is. I generally plate her food, because she loves to be catered to, but on those occasions where she makes toast or a sandwich...how so much mess can come from so simple a task, idk.
She'll put the knife caked with butter and jam (another peeve) down directly on the counter and just walk off and leave it, things like that. Drives me crazy.
I do that with soups and stews, but if I need minced thyme for a savory scone or an omelette, I'm plucking those blasted leaves.
It's due to how things rattle and move around during the wash cycle. They bump into things and lose their edge.
