Yes; I would imagine it is. Why would somebody who neither liked more saw the point in Marmite, who only ever came into contact with it in the cupboards of other people (and then, sometimes, mocked them for their taste in spread, if they were foolish enough to try to justify it by pointing out how nutritious or tasty it is, to them), suddenly find himself in possession of a jar of his own?

It turns out that liking Marmite is not a prerequisite to owning it.
