Park artist– how do you deal with it?

Hello, I’m new here and I’m coming with a stupid question. Something happened to me this morning on a supermarket parking lot where I would like to know how to behave correctly in such cases. The following had happened: I wanted to make the last purchases this morning and drove my husband’s car to the next supermarket. With my two little children in my luggage (2 years and 7 months). I also immediately found a parking space (suitable for my female requirements) . I have to say that since my little son is still being transported in the baby bowl, I also take care of enough distance to get the door wide enough. So far so good, I’m done shopping, come back to the car and what is there of course?! A parking artist at my passenger side. This hero of the road traffic has so skilfully parked that I could not even open the door on the passenger side. Getting the baby bowl into the car was not even to think n. From the other side I couldn’t put them in the car either, because my daughter’s child seat is stuck. So I was waiting, waiting and waiting (there were only zero degrees this morning) After half an hour in which I didn’t get the baby bowl in the car I went back to the supermarket and asked the branch manager there for help, which then answered me that I should look for a witness, wait five minutes and then call the police. , done and when I just wanted to call the police came the nice Mr. Park artist. He was of course not aware of any fault, then turned on me still stupid about what I actually wanted. When I then answered in his tone and pointed out that I could not put my baby in the car because of him he then left some indefinable things away. I then pointed him out that if he had something to tell me to do this in a clear tone And now I would call the police. Then the good gentleman became very small and was very concerned that the gentlemen would not be called by the police. The ironic thing about the whole thing is, he himself had a child with him. And since he had parked so stupidly, he had to balance his daughter over the driver’s side to the passenger side until she was sitting in your child’s seat. Now to my question, how do you behave right now in such cases? Really call the police ? And if so, what do they do then? Thanks for the answers
