Nice job. Since I am local, do you mind if I inquire as to the diner you were at? (You can PM me if you don't want to post it here).
Your story reminds me of a story that my Mom used to tell us once ina while. She was a teller at a bank in Owosso that was held up by a MWAG. The man left the branch on foot and my Mom followed him for quite a few blocks until the police caught up to him. She was a great witness, although maybe not so smart for chasing down an armed man who just held up a bank, especially given that she was only 4' 11 and maybe 100 poundsat the time!!
