My husband has the toaster set on the lowest number. I always
SAY, "You're bread is warmed". But I'm
THINKING, "You could have microwaved it for 10 seconds and got the same results".

To each his own.
It's kind of funny though because when I'm done with the toaster, I leave it set on high. He leaves it set on #1. So when I make toast, it pops up when it's still warm bread and I have to turn it up and pop it down again.
When he makes it and forgets to readjust the dial, he has to start over.
We used to have a four slice toaster and I always thought it would have been smart for us to have 'assigned slots'. You take one side, I'll take the other. But it couldn't work because one side sometimes burned it even more than what I like.
