Just a heads up that tip is already included in the bill at the bar. They never gave me a receipt so I had no idea. Server brought my change and waited for me to leave a tip. I left him a tip based on the total he gave me. I then started thinking about how my bill was way too much so I asked to see my receipt. He said they don't keep receipts for cash. Well, then he suddenly finds the receipt in his pocket. I discovered how the tip was already charged and how he collected more tip from me. I confronted him. I felt so upset that he tried to get away with a double tip.
