I was threatened and intimidated by an employee named Diane at the circle k on first and ft.Lowell. she then began to yell scream and curse at me in front of others customers including children. I only asked to buy a soda to break a $100 and she refused me service and began yelling and screaming in my face. She refused to give me her name so I could file a complaint and covered her name tag and began to try to intimidate me by her threats. I left the store so the situation wouldn't escalate.
