Another price issue at my Russian store

Tweet

So I was at the Russian store yesterday. Decided to get some ground beef. They were out of regular ground beef. Only had ground wagyu beef, which of course is more expensive. Decided to get it anyway, as we rarely buy it. The shelf said it was $8.99. When the (new) cashier scanned it, it came out to $9.99. I told her about it. She told me she doesn't make up the price and then proceeded to look at that item on her register screen. When she was done she told me something along the lines of... sometimes the price on the shelf is not what's in the system. She has no control over that. She then asked me if I still want the item. I told her I do. What I should have done though, was tell her something like: Yes, I still want it but at $8.99. You should adjust the price. If you can't do that call the manager... Instead I let it go and now it's bugging me. Just like it's bugging me that I didn't speak up when she rung up the container of sour cabbage as salads/mushrooms/carrots from the salad bar. I am not sure how much the sour cabbage usually is per pound but it is definitely nowhere near $6.49/pound. It should be closer in price to pickles ($2.79/pound), if not the same price. That's a big difference in the cost. I decided not to deal with that because I was sure she doesn't know what the heck sour cabbage even is and wouldn't be able to do anything about the price issue. Heck, when she was scanning stuff from the produce department I had to tell what was what. This is a red onion; this is sweet vidalia onion; this is a cubanelle pepper; this is cilantro, etc. I get that she is new to the store but she should still know what item she is scanning without me having to tell her...
