Give Me the Secret Sauce, Stepbro! Waitress War Swap

My stepsister and I have always wanted to own a small maid cafe, but running it is not easy, especially when a new sports restaurant opened right next to our business. They were only successful because of their secret sauce recipe, so we decided to play a few games with our competitors to get their recipe. They were also step-siblings, so we knew a family-friendly truth or dare game would be enough.
