I know lots of people don’t like to see signs, or put up signs, but I am tempted to label everything in my house and put up signs with explicit instructions on how to operate everything.
I have a Ninja coffee machine with a stainless steel thermal carafe. You can’t see through it like you can a glass carafe.
Upon welcoming guests into my home I point to the coffee maker and tell them there will be a fresh pot of coffee waiting for them in the morning.
Guest gets up and decides to feel the outside of the carafe to see if there’s still hot coffee. Well, it’s thermal, so the outside is cool to the touch. Guest decides that since the pot is cool, all the hot coffee must be gone. Doesn’t think to pick the carafe up. So he takes it upon himself to make a fresh pot. He finds the filters and coffee, sets it all up and turns on the machine. Mind you, the carafe was full of coffee. So, the coffee machine does its thing, and the carafe overflows, all over my counter, into the silverware drawer underneath, down the front of the lower cabinet and all over my tile floor with pristine white grout.
As a host, I do my best to anticipate things guests won’t understand, but jeez!
