Not a good store cashier does not no how to attend people

I just went to purchase 1 item seen family size Oreo picked up at pack because it was tagged 3 dollars. Went self check out oreo's rang up 3.59. Notified the attend she corrected the issue with no problem. So when when your be checked out make SURE you pay attention to the prices of all your items. Only thing I didn't like so much is that it's 1 way in and 1 way out.

Went last week the cashiers was so very helpful.
