First I am happy you are safe. I have to play the Devil's Advocate here with my 2 cents, what I am thinking here is this was some type of security personnel. Even though he had blue jeans on it is not uncommon for security to go undercover in a store, if they are intent on catching someone (I have run into plain clothes security in these type of places before). You probably became suspicious to him, first because you were crossdressed he may have thought/ stereotyped you were CD in order to hide yourself to commit a crime and second because you didn't acknowledge him when he said "excuse me." Do you get tense/ over anxious any when you are out in public in the mall (just from being crossdressed?) and were you that day? Someone acting nervous (body language, facial expression, isolating oneself) are always going to be behaviors that law enforcement personnel are trained to look for). I know from my own experiences and attitude I have learned this.
Maybe go back to the store in drab and check this guy out?
