i didnt have a huge problem with this until one time i was at the mall with my then boyfriend and his mom and we were leaving barnes and nobles and the thing went off we all looked confused and walked back in and it went off again then we left one by one and it was just me the cashier said sometimes certain types of clothing or just too many people going through at once can confuse it but ever since then im extremely paranoid that theyll go off for me and ill get in trouble because someone will think im stealing
