Mr. Buttsniffer (pronounced Bo-snifer) is the manager of Burger on a Bun.

When he hired Marvin, he said twice Marvin needs to get diagnosed because of his weirdness. He eventually made Marvin assisant manager, but then Marvin quit when he fired Teri and Brianna when he was taking the job too seriously and realized family is more important than work.

Mr. Buttsniffer taught Marvin a lesson about how teamwork is important in a restaurant, and that he didn't need to take his work so seriously.
