I love pizza, but it doesn’t always love me. I’ve got allergies/health issues, and the only pizza I can (sometimes) safely eat is cheese, but I would never say a word if there wasn’t any plain cheese pizza. I’d either find a piece with minimal toppings I could discreetly remove or just eat something else, especially if I was brand-new to the office. Grown adults shouldn’t throw fits that would make a cranky tween blush, especially in the workplace.
