I've been doing this at Bruins games for a few years. Hardly a big deal if you like hockey.
Other than the Blackhawks / Bruins game in the stadium this NYD it's been many years. I suppose this is one more way the world has changed since 9/11.
It actually takes as long to scan the tickets.
Of course all these professional venues that manage this well are not ND staff - I'm sure we'll find a way to f*ck this up. But I believe this was inevitable.
To quote a famous coach "Get used to it"
if that's a barrier for somebody to attend a game, either (1) they don't care that much about attending or (2) they need to answer a few obvious questions.
