How do you know beforehand what smells others dislike? What happens when the cumulative dislikes of food smells makes it impossible to bring in most meals? My partner is a vegetarian and doesn't like the smell of meat. Would you stop eating all your meat dishes in the office? What happens when someone who was "banned" from eating or heating their food in the office fights back by suddenly banning other foods?
