Am I in the wrong?

I had to go to the DMV and I sat in the middle chair where there was 5 empty chair to the left of me and 5 empty chairs to the right of me. This lady and her son came in and sat to the right of me where there was an empty chair between us. The lady’s mom came in a few minutes later and sat right next to me to sit with her daughter and grandson. She then asks me if I could get up and move so she could have some space.

I am already annoyed and aggravated by that I have to go to the DMV and was already asked by a guy if I could go to my car and charge his phone up because it was dead and his insurance card was on his phone. I didn’t pay any mind to the guy and I just told the lady that I was already here for 35 minutes and that I wasn’t moving. She wasn’t too happy but I wasn’t happy either and the shite those two people asked me I was just dumbfounded.

I could never ask somebody to move who was already sitting down while I sit right next to that person and I would never ask somebody to go to their car while they are in line at the DMV and ask them to charge my phone. I felt like Jim Carrey on Me Myself and Irene when he snapped in the store.
