I know something about this kind of thing Binge. You can get your money back or get your dignity back but you cant have both. Iv never been able to anyway Wrong way: My suggestion would be catch him in the bathroom (lockable door) of a public place and punch him in the stomach and sides. Stay away from head and neck shots. No face trauma means no assault. Also make sure there is no witnesses also. Your word against his means you walk away. FYI I do not condone this but I saw it in a cartoon once Right way: You can do the right thing and take him to court or wait it out and let karma get him. If he has a job you could always show up at his place of employment. People tend to treat you different when their boss is watching. Hell make a scene! Its fun trust me.
