i didn't read any other replies, but it's almost like stalking and harassment, i would take a picture of her on your cell or maybe even film what she's saying and give the info to the police soo they can get a restraining order... lol i dunno maybe that's a little much but if she really just comes in to make fun of you then she should not be allowed to enter that store anymore. it's causing you soo much stress and making you miserable, this can't just go on.
