i agree about the phone call - however, just a couple of days ago, my cell phone battery died on me, i got back to the commuter lot and was supposed to call my wife to come and pick me up... needless to say, that there are no more public phones easily available on the streets any longer, and there was nobody around on the parking lot (I got to the lot a bit earlier then normal) to "borrow" a cell phone... ended up waiting until wife decided that it was time to come and pick me up... Of course, this was not life threatening situation, so I just sat on the bench, and waited...

It just may so happen, that a phone might not be an available option...
