if you purchased tickets together using the 'friends & family' option on the website, check that your seats are actually on the same row. scrutinised my tickets out of idle curiosity/boredom the other day only to find that, for some bizarre reason, the box office brains interpreted 'together' as being in adjacent seats on separate rows [insert face palm here]. had to go to the stadium to change the tickets and be relocated so we're, you know, actually together.
