Would you have gotten upset?  

I would have been very upset, but now a days I'm afraid to say anything course you never know what kinda crazy person you're dealing with.
They might pull a gun on you and shoot you over a parking spot.
In the good old days I gave people the finger and told them to F off but it's
getting nasty in this world.

I just look at them crazy, and then park elsewhere. I only said something to one woman, and that is because she got so close that she almost hit me. I did mention that, and she was, of course, not friendly.

It's a good thing he gave him a parking space and he didn't went angry on yah. nice move. maybe that guy gotten used that parking space for a long time. and it wasn't his day when some one else was trying to into his parking space like his own territory

Parking space is a major issue of contention in urban life. Ye if I were in the wrong end of such a situation I would be upset. The issue would be, was I a slow poke and did not get the space or was I crowded out or cut out of it. The second one is definitely an offense and I would be mad.

I have a space in the parking lot at office. It is at the end so I have a wall on one side and need to be very careful while parking. I usually park close to the wall as that gives me more space on the driver's side. On one Friday I found a car parked so close to mine that I had no way to get in! I waited a couple of hours and called the security. The other person as I was told, had gone for a weekend party and promised to remove the car on Monday. You have no idea how mad I was. I deflated both of the back tires, and called the tow. On Monday the offender came and, was told of the towing, paid his fine and claimed his wreck.

If I had been cut off I would have been very pissed but knowing the world (and parking places) have their share of nut cases. I would not get out my car and put myself in potential danger (road rage). I would (and have done) given them the finger, muttered under my breath and moved on. To live and find another parking place.

I think it is only natural to feel upset over incidents such as people stealing your parking space but to get out and confront someone who may or may not be stable is foolish in this day and age. There have been many reports of road rage and situations where people have been hurt. Personally I value my safety more than parking spaces so although unhappy I would quietly move on to another space and hope that Karma prevails!

Oh, I'd likely be mad, but it'd be one of those thing's where I'd yell "F*cking moron!" out the window and then look for another place to park.

Now that I don't have my health anymore, and am terminally ill and in a wheelchair, I reret all the times I have gotten angry over something so trivial as a parking spot. Now that I can't drive anymore, I would do anything to drive agan and look for parking spots. If someone takes your parking spot, wait for another one or go elsewhere in the parking lot and get another spot. And don't get into a fight because you never know what that can escalate into. You could end up very hurt, hurt someone, end up in jail, or worse. Over a parking spot. Think about it.

Over here in Italy it's the same. Parking spaces are becoming the cause of many injuries due to rage and last month one poor indivdual was killed after being pushed by an angry person. He fell and hit his head on the pavement and he was not even partly involved in the squabble because he, like you, was just the third party. There is just no more respect for human life and it is appalling.

I have had the space that I was eyeing up taken by some idiotic driver who got in quicker in the past too. Like others have said above, I just move on and think of certain exclamations without saying them outloud. I dare not think of the consequences if I was overheard so I mutter and move on

see it all the time here, i would have asked the dude if he could please move his car so i could have gotten out.
but i dont get to upset over it if someone take my spot. i might just say thanks alot A$$ hole. but once at the gast station i kept having people cutting me off to get to a the pump, so i finally said screwed and cut someone else off. i told them loud enough for the other four people to hear just some rude a$$es around here isn't there.
