I’ll Have The Allergen Pizza

I am working as a waitress.

Me: “Good evening. What can I get for you?”

Customer: “I am not sure; I am allergic to vegetables. Actually, I will take the medium pizza.”

Me: “Oh, I am sorry. The base is tomato puree and it is topped with a number of different veggies.”

Customer: “Oh, I am not allergic when they are on pizza.”
