Christmas shopping and wrapping after work till 1am. Stop at denny's because I hadn't eaten since 9am before work; worst experience I ever had. Cook cranking bar hip hop over the Christmas music playing on speakers....so two different musics competing and thennnn; waitress never brings bill so we walk up to register to pay our waitress. She gives me one receipt and asks if I wanna add anything to it. I asked her don't I put that on receipt? She tells me no we have an old system and says here you can put it on this one and hands me a different receipt. Husband says I have cash for tip to me. I am now questioning the two different receipts and asked how much was my bill, how much did you charge me. Then she was fumbling through receipts and says oh I over charged you. Can I just give you cash back. I ask "what do you mean, I don't understand, explain?" She charged me 20% over my bill (Bill was 20$ that she handed me but then rang it for 24$ and change) Lol then SHE tells ME it wasn't for a tip it was a mistake (I didn't accuse her of anything i didn't say a word lol i just wanted to leave). I went back and took the 7$ off the table and left the 4$ she ACCIDENTALLY over charged me and felt her self worth. Lol what a experience. WOW! NEVER AGAIN! Food was less than ok as well.
