Ha! Simply clever. You may want to add an optional tweet link that generates a screenshot message, "Chad just tipped his server Judy 22% less because she is a woman" or maybe a link in the app that says, "Show the world what a sexist cheapskate you are by using Toothpick to tip" something with a tweet out link to keep the rage rock rolling. Well done Amy!
