Ordered the eggs benedict and paid in cash. I get my change back from the female bartender and she shorted me on my change. I confronted her about it and she said "they don't have nickels" and that was why she was shortchanging me. She was standing as far back from me as possible probably because she knew she was trying to rip me off and I might potentially attack her. She got the manager who then told me some lie about why they don't give correct change. Everything he said to me was bs. He finally gave in and gave me correct change. I don't trust these people. I'll never go back..
