Currently shopping for new appliances. A salesman mentioned to my wife that some of the newer ovens that also air fry can't be placed up against the rear wall unless it is fire rated. I can find nothing about this online. She didn't question it because he started calling her "Hun." After the third or forth Hun, she had to leave before being dragged out of there. As a construction project manager for thirty years, she doesn't take that lightly, without somebody getting hurt.
