Very rude staff!!!

Was parked in the parking lot and after coming out Of the store after purchasing some items hey lady come screaming at me to move my vehicle.i'm not in any kind of no parking zone or any restricted parking area no signs posted saying otherwise and I tell her that I also let her know that I was in the store purchasing items as she continues to scream at me to move my vehicle for a delivery truck that wanted to park there. Will never go back to the store ever!
