[flashpig]

And I have heard it used, though I don't think i applies in this case, to mean feeling grumpy or in a not 100% good mood.

[Sequin]

Having to go for treatments suggests a medical rather than emotional cause

[Peter Pedant]

The person who has to get Elizabeth ready in twenty minutes - getting a lady of any age ready in less than two hours is a non-starter - may also feel that the request is a 'bit off' (= a non-starter) and may also feel a bit off about it all (= irritated)

So all in all, a bit off is a phrase which is a bit of alright!
