Problem with Non English speaking Apparel Associate that keeps cutting the self checkout lines. Last night she pissed me off and no one is doing goddamn thing about it

So we have this old lady associate that only speaks Spanish she's been working in apparel for a couple years. She constantly cuts the line at the self checkout when she leaves to cash out what she is buying. She constantly cuts the self checkout line and whenever I try to signal to her there's a line she just yells at me in Spanish and continues with her line cutting. Now last night there wasn't a line but all the machines were occupied but this time she started scanning her items at a register another customer was still occupying and hadn't finished paying yet. The customer was like "what the hell are you doing I'm not finished yet! I'm like trying to signal to her that he's not done yet and you have to wait for your turn. Then she asks if she can pay with a card in Spanish (I know what card means in Spanish). She still is trying to scan her items at the occupied register. I'm like he's not done yet and I say "I know you don't understand English but ABRE LOS OJOS!!!". She finally got the message but gave me a look like I'm an asshole. Is there anyway I can get someone to talk to her to tell her she can't be cutting lines like that? Nothing has been getting done about it.
