Jack In The Box review: Customer service

The cashier at the window was very rude, slam the window shut after I kept asking why was my total was so high, and she got smart at the mouth talking about that's what the screen says, that is not what I asked, come to find out she charge me the medium price instead of the small price, plus she did not ask if I wanted small medium or large... You just don't do that.. She needs more training on customer service, because if it was the young version of me I would have gotten out the car on that girl attitude.
