I have discovered that in order to get people to do things the way you ask, lives must depend on it.

I will give you an example. Mushrooms are not only an object of my spite, but I also live in abject terror of their mysterious properties. However, I like pizza, especially calzone. My local pizza manufacturer makes calzone but they have mushrooms in it. If I ask for "one calzone, no mushrooms" they will ignore me and put the horrible fungus in my folded pizza! However a simple change of tack - "One calzone, no mushrooms. I am alergic to them. If there are mushrooms in it, I will die instantly upon ingestion so it is very important." then I will get what I want.

Nyquist has a loathing of sauce, similar to mine of mushrooms except that unlike myself, his fear is totally irrational. He likes burritos from a local restaurant but they always come with sour cream (which is tantamount to sauce) no matter how he asks. One day I interjected "If you give him sour cream he will die, he is severely alergic." Guess what? No fucking cream.

Case closed.
