One of the first offices I worked in had a sign by the floor microwave: "No fish!," it said. While I laughed this off at the time as being a bit picky, it wasn't until I worked close to another office's kitchen that I realized how pervasive reheated mahi-mahi could be. While it may not seem like a little warmed salmon, heavily splashed Chanel No. 5, or post-vacation durian could mean that much, it's no laughing matter. A smell issue could harm workers and even land an employer in legal hot water if they don't think a stink means a thing.
