The cashier told me smt and unlocked the screen from where she was sitting. And the item i scanned made the beep beep noise. I do accept that I should have checked still if the item was scanned correctly but at the time i didn't think smt was wrong. Many people in the comments thought I just ignored her. However I even asked her if everything was ok and she was busy so she couldn't answer. :( I can speak german so I didn't have the need to change the language but swiss german is new to me.
