i would say, until he's in a similar situation, he can't say what he'll do. hell, when i got robbed once, i was sarcastic as hell with the guy, and oddly not even scared, just annoyed that:
1: i used a payphone i knew i shouldn't've been on, due to the crime rate in the area at the time.

2: i was not looking out around me, just looking down at the phone booth itself, getting ready to finish the call.

what you do is what you do when the issue happens. nothing more, nothing less.
