There's an old woman where I work who loves to eat burnt popcorn every day. She intentionally burns it in the microwave during break and insensitively ruins the air we breath with this oder, every single day. Noone will sit near her and she was even told by management once to stop which lasted about a week. She caught the microwave on fire one time but she still insist on making her daily snack of freshly burnt popcorn regardless.
