Conan O’Brien says he caught Larry David arguing with a waiter over mustard and had to remind him there were no cameras “Literally a week ago I walk into a restaurant... Larry David’s there with his lovely wife... Larry’s in the middle of getting into it with the waiter because the waiter brought him a turkey sandwich with no mustard” “He’s like, ‘In the history of sandwiches, when has mustard not been part of the equation?’” “I said to him, ‘Larry, there’s no cameras’... He just said, ‘I would like to be paid by HBO to be the guy I am anyway’”
