I don't drive, neither does DP. We had a friend round yesterday who does, and she parked in the only available space in our crowded street- in front of a garage that was numbered 42. Trying not to dripfeed- there are many garages in our road and as far as we are aware the numbers on them do not relate to the house numbers- for instance we live in #67 and our garage is #1.
When we moved here a few months ago we asked the local housing association if there were any private parking spaces we needed to be aware of. We were informed that no, the street was a first come first served basis regarding parking. Apart from my neighbours one disabled space, as he is the only disabled person in the street so gets private use of this space.
Anyway, friend was parked for 10 minutes, came back out to find a note stuck to her windshield and a large car parked right in front of hers, blocking her in.
"If you want to get out, come to #42"
We went to #42, knocked, bloke answered the door and started shouting, demanded we apologise to him. This was before we'd shown the note, my guess is he was watching us through the window or something.
Friend said
"Excuse me but I would have apologised had you not just been so rude, I wasn't aware of any allocated spaces, please move your car, I need to get out"
He slammed the door in our faces 
His wife trundled outside 5 minutes later and was just as rude. Stood next to her car and said "Oooh you could probably get out through that spot, couldn't you?". We both looked at her like
errrr... Said we could probably but not without damaging her car, and could she please hurry up and move it- we were trying to get to the shops before closing time!
Cue lots of huffing and puffing on her side as she verrrryyy slowwllyyy moved her car.
I don't like getting into a disagreement with neighbours or anyone and wish this could have been avoided. IMO they were very very rude and it is a simple mistake anyone could make- I want to avoid this happening again so would like to know if there is any way to find out if the info our housing association gave us is correct?
Is there a way to find out if someone owns a parking space, or rents or whatever?
I'll be driving in a few months myself so really don't want to upset any more grumpy ass neighbours.
