I feel walking up, talking on the phone, sounding pissed while flipping through the pages alone would open a lot of doors. Don't need to be too charismatic when you look like some tiny bullshit away from crimes against humanity.
Then you just wait until somebody enters in.
When the person opens the door you run to them and yell "wait wait wait" while frantically gesturing. After you enter - say quick "thank you" and disappear.
