Why am I being followed by certain customers?

Hi it seems like every retail I have worked at I am being followed by certain customers and this is unfair. I have been getting followed by a red headed guy who just won’t stop following me or watching me! It is very creepy and someone is doing this on purpose! Then there is this lady who is a Karen and she is always stealing at the stores I work at and getting away with Everything! She needs to go bother some one else! I don’t need to be dealing with these same ongoing customers who keep stealing and watching me at the stores I work in! Find someone else to bother and Harrass you are mistaken me for some one else! Leave me alone! The cops know and you better watch yourself!
