I worry about the toaster as it normally (not in use) sits at the back of the counter, but I insist we pull it out to outside edge when used as don't want the cabinet finish getting hot. Drives me crazy that DH won't always close the glass doors of the fireplace (always uses the metal mesh screen instead) and the varnish on the underside of the mantel gets hot and bubbley--I threaten him about this every time.
