Look! if you bullshit me we'll end badly here eh

I was stopped by a police car in 2019 before the first covid-19 wave started, while I was cycling to Officina Meca (an association that promotes regular musical programming at the Ferrara skyscraper). One of the members of the association invited me to see a film. In that year, I was attending high school (evening course), when I finished class I took my bike straight to the skyscraper but it was already late, I was coming from via Garibaldi and as soon as I crossed Corso Isonzo I took via Arturo Casoli and after 50m I saw a police car coming at 40 km/h, which then immediately stopped in front of me, there were two of them in the car and the one next to the one driving, lowered the window then asked me to provide the identity documents and I took my wallet out of my pocket and showed him and after checking my id, the police officer asked me again when my permit as due to expire and I kindly answered him with respect but the police officer didn't trust me, then he said to me with a harsh tone "Look! if you bullshit me we'll end badly here eh" I replied that I wasn't lying and to make him believe he called my tutor for confirmation and while I was talking to my tutor, the police officer said to me "it's okay you don't need to call" after which before he gave me the document back he asked me again where I was going and I answered him kindly and finally they let me go.
