Food Lion complaint: Horrible customer Service at Food Lion

Okay, so first of all today is November 23 2022. I just had THE MOST HORRIBLE experience with 2 cashiers. 1 was on number 2 lane, time is about 9:30 am.
They had 2 cashiers at first so there was long lines …then a black lady sorry don’t know her name…she opens cash register 2…then when I was trying to pay for my food… there was misunderstanding because I already swiped my card and it didn’t process..so I was trying to understand why there was still total of 32 dollars… anyways I guess there was a question on screen that I had to answer that I didn’t know yet or see it…because I was just shocked how the cashier attitude was towards me . Then…. let me remind you of the long line behind me of tons people waiting….then she wants to say to me that she doesn’t have to ring me up!!! And she was very argumentative and kept with nasty comments.
Like omg .. I NEVER EVER been treated so horrible before like that at a store.
Then when I asked for her boss they wouldn’t do that.
