At a few shows, I've given up pretty good seats. In Dallas, I met a guy on the lawn and gave him my 5th row center for the second set and encore. I saw the rest of the show from the lawn and had a better time with some cool people that were his friends. In Chicago, I met a girl before the show with eyesight issues who was sitting waaaaay back, and I gave her and her friend my Geddy-side 3rd row tix at intermission. My brother, who's ticket I also gave away, was cool with it (I bought the tix so he couldn't gripe much), and I found out that by sitting waaaaay back, you can see parts of the show like the lighting that you miss when you're up close. Other times, I've let people borrow my close up seats for a few songs. A few times in Kansas City, I gave a randomly picked dad and his son second row center seats for a few songs, while I sat back in row 45 or thereabouts. Both times, the kid came back with eyes wide and a story to tell his friends, and the dad looked like a hero, while I missed being up close for a few songs that I saw from up close on other stops on the tour anyway. Don't know what I would have done if dad and son didn't come back from my seats, of course; maybe that would be a better story anyway.
I am aware that I have been almost impossibly fortunate in my life. I believe that when you're fortunate to be able to afford really good seats, you can share the experience with some real fans who haven't been as fortunate, and get more out of the deal in the long run anyway.
