Have you already tried telling her point blank (in a polite but concise manner of course) exactly what actions she performs that bother you consistently? If you haven't, you should. People aren't mind readers and unless they know something is bothering you they'll continue to do that behavior because it's being allowed/not addressed.

....okay let me learn from this and stop pulling my partner’s stickers thinking I’m helping........

I have the exact same problem.

Many of my partners do this thing where all cups pass through hot bar first. That way, they can pump syrups like hazelnut or toffee nut that aren’t on the cold bar in and add any necessary milk so cold bar is all set up. If hot bar is slammed, the cold bar partner can very easily help set them up and get pitchers and syrups ready so all they need to do is steam the milk, pull the shots, and hand it off. It’s very convenient.

There is one partner I have who HATES doing that. She also never likes doing cold bar. So whenever I’m on hot bar, if she’s on reg and stickering cups, she separates them by hot and cold bar drinks which throws off the dynamic everyone else in my store has. That means a lot of times, if a cold bar partner comes in to get toffee nut syrup and I’m doing my sequencing we bump or clash in some way that throws EVERYTHING off. When that said partner is on cold bar, she likes to pull all my shots for me and completely take over our second espresso machine, completely jumps cups in the queue, etc. She will do ANYTHING to take over hot bar. So her drinks pile up on cold bar. I used to give in and just move over there and start doing the cold bar drinks, but I’ve stopped doing that and it truly has been screwing with her, because now all the angry customers yell about how their grande black iced coffee cup has been sitting right in front of our iced coffee for 15 minutes when I’m trying to do the job I am supposed to be doing.

Sorry for the rant under your rant, but just know I feel your pain and I sympathize with you. Don’t give in to that partner. Talk to your shifts or your SM about it. They’ll get called out eventually.

Talk to your shift or your SM and get them to talk to that person. I have a few partners that do this even when they're NOT on either bar. I'm in the middle of a sequence and they'll just go over and finish my drink for me under the guise of 'I didn't want the shots to die' or 'I just want to do something other than take money' Shots take 10-20 seconds to die. It literally just stopped pouring. Don't think me an idiot.

I once said to them "please do not interrupt a planted position like bar unless you are asked because we're in the middle of a sequence that you know nothing about and it can really screw us up" but they still do it every now and then. Don't pull my stickers, don't start making my drinks unless I ask and don't touch my bar unless you are told to be on that position. END OF STORY.

Not going to lie this is how I feel about my SM when I work peak with him. He typically DTOs and Im on DT bar. We never really have a partner stationed at cold bar so typically our Mobile/Cafe partner will do cold bar. On the days when that isn’t feasible, I’ll sometimes have to run to do an iced tea quickly and then I’m right back (usually I’ll steam milk and then queue shots before I run off) but he always comes over and finishes my drinks which throws me off. Like i put the cups where I know they are and they get moved whenever he is DTO. I have had to remake so many americanos because I accidentally poured milk into them because there was a latte cup in that spot when I left. Like i have my system, i know what I’m doing. I only genuinely enjoy barring with about half of my partners. Like i know they think they’re helping so I feel bad if I were to say anything.

omg i hate when a partner comes and pulls out all the stickers and stickers the cups. that shit fucks with me

Not pulling stickers, though, completely throws off sequencing soooooo...
