I was just about to withdraw some money from the cash dispenser outside of the bank, a situation in which I always feel a bit vulnerable, when I was tapped on the shoulder by an aggressive drunk (at nine o'clock on a Monday morning) who told me that he knew my PIN number.
I told him that he didn't know my PIN number, and that there was no way in which he would ever find out what it is.
I then told him that if he didn't step away and leave me alone I would hit him extremely hard; I didn't need to swear or shout, I just informed him what would happen if he didn't modify his behaviour.
Fortunately, he wasn't that drunk that he didn't understand.
