We don't have direct experience in this at Universal, but considering how awesome the TMs were, I bet they are just like the CMs at Disney (and they sometimes are, literally, the same people), and do things quietly and kindly. I woudnl't worry about being shamed or anything by the TMs. The modified seats are the ones on the outsides of the "benches". Look at the 4 seat bench, head to the outer seats. I think she's saying that the outside seats are actually *bigger* than the inside ones? Though the seats themselves aren't the the things that were modified; it was the harnesses, as far as I read.
