I would get upset if some douche in front of me would not sit down when I paid 150 dollars to have a seat. If you want to stand go back to the grass. I have a bad knee and it is physically impossible for me to stand for 3 hours.
I saw two guys get into a fight at S & A tour in Dallas because some guys would not sit down and his wife couldn't see the show.
I love RUSH and I can enjoy them in my seat.
Just my two bits.
