No, it was not a good thing in this day and age. I see that quite a few of you guys are too harsh and critically paranoid almost. Not everyone is a bad guy and I think perhaps some look too hard for the bad guy.
May I suggest that people need to chill out and take a lesson from the bankers. They don't teach the tellers how to spot counterfeit money. They teach the tellers how to spot good money, understand?
Learn about body language and most of the spookies will go away for you. I'd bet money that the old guys was non-threatening in his actions and the OP just didn't know what to look for and got paranoid.
