Input: This happened a few months ago, and I am not sure about my actions here. I believe I was right in standing my ground, but friends have spoken against me.

&amp;#x200B;

There was a big concert of a local group in a theater in my hometown, tickets were sold out weeks before the event and me and my girlfriend had to buy from re-sellers. 

&amp;#x200B;

Now, the tickets weren't numbered, so the seats would be grabbed on a first come, first served basis. We arrived \~ 3 hours before doors opened and we queued up. There were already \~50 persons ahead of us. More and more people started arriving, and the queue in front of us was "fattening up" with people who either arrived to "greet" friends and just stayed there, or straight up people who had a spot being saved for them. 

&amp;#x200B;

We finally got inside, behind possibly 100 people now, and headed for the front rows. The frontmost rows were already taken, but I saw 2 comfy spots next to a middle age couple in the \~8th row. I go over to them and proceed to START sitting on them with my girlfriend when the couple informs me that both of those seats are being saved. Bummer. No issue however, in the middle of same row there are still around 7 free seats we could take. We apologize and move on.

&amp;#x200B;

Turns out that there was one girl in her 20s next to those 7 free seats, and as soon as we are going to sit she says "Sorry, those are taken" To which I reply "...all of them?" "Yup...". I get more annoyed and start looking towards the rest of the rows of the theater and see a massive flow of people just sitting everywhere else. If we were to exit the row we pretty much would have to go all the way to the back by now, making all our time queuing outside a waste.

&amp;#x200B;

I felt not only annoyed, but I also felt saving spots like this was a severe disrespect. There are people like me and my girlfriend who stood for hours outside, and a single person who may or may have not queued properly was not saving 7 spots for someone who had not arrived yet. So I stood my ground and sit down on the saved spots. The girl complained, and I explained my reasoning, with a very defensive and slightly upset tone. My girlfriend tensed up, and you could see she didn't like the ongoing conflict. Eventually an older lady (40s) arrived, possibly her mother, and upon hearing from the situation she confronted me, but I stood my ground again and when the lady raised her tone, so did I. 

&amp;#x200B;

At this point, I am not sure if people from many rows away heard our little dispute, but I'm pretty sure it got loud enough for someone to focus and hear. The lady gave up and just sat down next to me, in possibly a passive aggressive attempt to get me to move. Didn't happen. Show started. The rest of the family arrived looking for their saved seats, almost half an hour after the show had started.  I even overheard one of them saying "I hate when people save spots, but now I had to do it." Two of them had to go elsewhere, and that was the end of it.

&amp;#x200B;

My girlfriend later told me she felt really uncomfortable, and was on the verge of simply getting up and leaving when I stood my ground. Another friend told me I need to control myself, and she WOULD have left there as soon as it all started.

&amp;#x200B;

I believe I was right to stand my ground, it was pretty much an abuse to save 7 whole spaces, and we had been outside for hours... but AITA here?
