Obviously, everything the waitress said was a lie that Andrew had designed. He had thought about the tipping tickets system from the beginning because in this world coins are used and they are not suitable for this kind of event, so he created some special tickets with his synthesis skill.
Although Andrew is not an expert, after studying some techniques to create paper, it was not difficult for him to create these tipping tickets with his skill. He took as a reference the design of the dollar bills from his previous life and only changed the words about the country and changed them to Heavenly Palace.
He also changed the name to "Pleasures" instead of dollars and the image of the historical characters of the USA to an image of the Heavenly Palace building. Many of the guests were asking the same question and when they found out immediately asked to buy Pleasures bills.
