Whistles and anything that makes a loud noise is great! I have this little keychain thing that has a pin you pull out like a grenade, it starts screaming loud as hell and flashes a strobe to disorient the person and scare them off. I think there are even versions of it that have GPS tracking and call the police to your location
okay phew because tbh, i hadn’t thought abt getting one until one day i went to cvs and i was getting out of my car, a man was getting into his car to leave but he was watching me go inside and the seconds later, he followed me in and then walked up to me and whispered smth in my ear and walked away to the bathroom and i paid for my shit and left as fast as i could
