You're very brave to willingly interact with Phillies fans!
I am OK with giving fans directions and making small talk about baseball as long as they are courteous
the metro can be a bit difficult. I once got free 100 level seats (an upgrade from the 400 level seats I had) for helping some Giants fans. Would be more reluctant to chat if I was on another team's turf.
And man that ump... ugh that hurts to watch.
