About five months back I was terminated from my place of employment. I was told that I was banned from the store. That company has a picnic every year. My girlfriend is currently working at the location and when she requested two tickets for us to attend, she was told that if I were to set foot at the picnic that I would be arrested on the spot and she would be wrote up for insubordination and possible terminated. My two questions are: Can I be banned from a store verbally? Can I be arrested for attending this picnic?
