You should always look in the oven before turning it on.
Seems simple to me. Before making the oven hot, make sure there’s nothing in there you don’t want to get hot (and that the racks are in the right place.) Takes maybe a second.
But a lot of people seem to find the idea that they (or anyone in their household) would ever leave something in the oven, when not cooking, to be deeply offensive.
