in the parking lot of the strip mall santa muerte temple in my neighborhood, a bicycle cop was shooing away a sex worker. he would ride very slowly behind her and flick his hand like he was herding a cat. she would talk about 4 steps and then stop and he would roll along and make the gesture again. she would again walk about 4 steps and then stop. i did not see if he ever got her to leave the parking lot or if she got him to give up.
