UPDATE: Had a customer yank my wrist out of anger
Okayyy this is mainly a nothingburger update but I know some commenters wanted an update and I know some people might be upset with how I'm going with this.
Long story short; nothing came out of it. I told all of my managers about the situation and even though they said they will get the AP guy to look at footage, it's been total silence about that. Which I get though as usual store managers are, they only care about cards and customer satisfaction. Here's where most people might get upset at me about; I'm not going to push for anything to happen as it was already almost a month ago and I have more important stuff in my life than to press charges against that customer. So, pretty much nothingburger like I said.
What did upset me a little though was that the same customer came back a few days ago and the manager who saw me break down in front of her due to it, told the jewelry associate to "be super nice to that customer" instead of you know, kicking her out the store. Manager didn't even tell me herself either that the customer was in the store, she had the jewelry associate tell me because I had to cover her lunch break while the customer was still there. I said fuck that and gave the keys to the CEC who understood. According to the CEC, the customer checked out and said some snarky shit about the CEC not ringing even though CECs are not allowed to ring at my store.
