There are some people who are not ethical and you have to deal with them on a day to day basis. There are not a lot of serious ethical issues, so you just have to work in the interest of good for all. There is not a group responsible for ethics. Life is about character. Who are you from the inside.
Life is about being fair, honest, truthful, and respectful in the work place.
Customers and people who you work with always need to be treated equally, even though they are different. Can't always do everything right, but you have to try. That Putt-Putt needs to provide a good project and a fun experience. Also a reasonable price for customers. Operate the business with fairness, honesty, truthfulness, morality, and equality.
