Should I leave my job I’ve only been at for a month?

I work at this place part time. I wasn’t fully trained and closing by myself. It wasn’t a problem until my coworker got really mad about signing someone up for a membership when no one told me I wasn’t supposed to do this. Then some guy starts coming in asking where I live and my diet…what time we close (I’m clearly closing) what time we open and if I work the next day. Reported to manager he said talk to security. Security was supposed to come while I open. Never did. On top of it I was locked out for 30 mins (don’t have key). I’m supposed to open again tomorrow by myself and still don’t feel safe. Im so stressed. Idk what the best thing to do in this whole situation. Idek if im getting locked out tomorrow again.
