who have run-ins with pushy salesmen that the responsibility is theirs to avoid the pushy salesmen and not the responsibility of the pushy salesmen who can't read and can't take a hint when they're not wanted and instead rely on their pushy sales tactics convincing people who don't need or want their product giving in just to get them to go away or buying the product because they don't understand what they're buying due to the salesmen using shady math and "facts" to push the product.
