I'm thinking this is a novice who decided to (learn to) cook during a high-pressure situation, such as a birthday, or some other special occasion. For most of these people, cooking means reheating takeout leftovers in the microwave oven. Their shiny new stainless steel appliances are for display purposes only, a function that would be undermined by the appearance of baked on stains from actual cooking spills and splatters.
Spills, spatter, and boil overs, like the one I created fixing lunch!
Anything is possible..every Thanksgiving many people get seriously injured, even killed, while attempting to deep-fry a turkey..
