Whoa, Angie would not have a job when I got done with her!
YOU don't go to another location. SHE needs to stop being a moroff. I doubt her management would be happy to hear she's doing that kind of stuff to people at their gym. Don't waste your time talking to her, go above her head and be done with her.
Don't let people like her mess with your mojo! Especially when you're trying so hard just to get to the gym and be healthy.
Kick some butt, girlfriend!
