How many people research a venue map? Who has time for that? I was planning on getting GAs so the seating map didn't apply to me anyway. Until GAs weren't available and I had to go for seats. It all worked out for me, because I was in the loop close to my show. But the majority of people who are buying seats to a U2 show are not checking out maps beforehand and are not on this site gathering information. They are trusting what the venue tells them, because why would they question it. The original poster has a right to be upset about the seating chart being flipped. As do the many, many others who have complained about it.
