Was IBU? It's really bothering me.
Yesterday after work I dropped my friend off at the shop near her house, as she wanted to pop in before going home. She lives just opposite the shop so after she got out the car I was going to drive to pick up my daughter from nursery.
She got out the car. This shop has a very small car park - one which has 4 spaces outside the shop,, and to get the the spaces you drive up a small drive on the left. You then drive out a small drive on the right to get out of the carpark and back onto the road.
The car infront of me stopped (it didn't bother to park in one of the spaces despite there being two free, just stopped in the drive which is meant to be for exiting) and the driver got out the car leaving his car door wide open so I was stuck behind his car because I couldn't get out with the door wide open. There was another car behind me which had just pulled out of a parking space and was waiting at an awkward angle to leave the car park after me. We were both stuck there because this idiot had stopped on the drive with his door wide open. I sat there for about 10 minutes wondering where the Hell he was (it's a tiny shop and my friend had walked out and left after about 3 minutes so I have no idea what was taking him so long!) I was not only getting the stage where I'd be late to pick up my daughter, but also a bit of a pile up was caused - there was the car behind me which was stuck at an awkward angle pulling out of a space, the person from the other car was sat in their car still in the space wanting to leave, and there was another car waiting to come into the carpark who couldn't even get in.
Idiot-who-left-the-door-open's (I assume) partner was in the passenger seat just playing on her phone, ignoring the commotion, until eventually we made eye contact. I looked at her with a bit of a 
expression and she yelled at me "WHAT?!! Just fing wait!!! He's just gone in the shop!!!" I replied "I'm in a bit of a rush..." She yelled back "I'm not getting out to shut his door!!! I'm fing 7 months pregnant!!!!!" And then started effing and blinding about how I should "just wait until he gets back and hears you've been stressing out a pregnant girl!!!" (I'd said nothing except "I'm in a bit of a rush."
The car behind me started beeping and I thought, sod this. I'm late for pick up, the cars behind me are getting angry too, and most of all she's basically just told me that she's going to tell this man to have a go at me when he gets back. I suffer from anxiety and was getting quite upset and worried and shaken between a combination of being late, being threatened, and being beeped at. I thought, I'm going to have to try and move. So I got out of my car and gently pushed the open door of his car closed. I closed it so gently that it didn't slam, didn't even close properly, but now I could just about inch past.
I started to inch past, very slowly and carefully, and this girl starts screaming abuse at me. I mean properly screaming, saying I should just fing wait and how dare I touch her property and that I'm going to scratch her car and that she's going to break my fing legs. I was quite shaken but continued to drive carefully and left the carpark without touching her car. As I was leaving, the car behind me was doing the same which she shouted and swore at him and threatened to break his legs too.
My question is - was I unreasonable not to wait? I KNOW he was unreasonable for leaving his door wide open knowing it would clearly block the entire drive, and she was unreasonable for getting instantly aggressive and threatening. But I just want to know what you would have all done?
