If an NPC of any sort says "Accept this spell" and the PC does, there is no save. I used this tatic to geas a whole party.
If there is deception, the PC, and other allies, should be able to make appropriate skill checks. Spot vs disguise, sense motive vs bluff, or even knowledge religion or spellcraft. The PC still has a chance of avoiding the effect, but not the save they thought they were getting.
A poison is a different matter, as mentioned, but the tatic is still good. The PC mind-bender is harder to call. I would break it down to a bluff vs. sense motive.
Just because a harmful spell is cast doesn't mean the target may not forgo their save. But the PC should always have a chance of finding out before it is too late.
