How would you handle a coworker like this?

Certain coworker, keeps trying to find ways to control my drawer. Claims she's doing things to "help" that often take just as long as if she'd let me handle it in the first place. Insists I "need" her, even when she just gets in the way. Talks about what a "good friend" she is, while constantly undermining me. Gaslights the boss into giving her the ability to dictate things to me, behind closed doors in secret, so I can't protest her manipulative antics, and have no play along. Hates that constantly malfunctioning self checkout thing as much as I do. Especially with the idiot customers who gum it up worse because they don't stop and think before messing it up. So she hijacks my drawer to count it down, and makes me handle the thing, but then won't let me figure it out. Interrupts what I'm doing, to make me sound stupid before I even have a chance to solve the problem, thus not saving any time. So her claim to hijacking my drawer to save time is a lie.

I get frustrated, and she basks in smug airs of superiority. She has the boss wrapped around her finger.
