Can a minor be a crew trainer at mcdonalds?

I know people who have been working as a crew trainer in Australia since they were 16, but you need to be proficient on your station, either front counter, drive thru, back area or sometimes mc'cafe. You also have to be friendly with the crew, supportive, understanding and follow correct procedures (no short cuts). If you don't like dealing with complaints, issues or new employees who are slower at doing things, then I don't recommend you become one. Also, you should be able to take control of situations, let the crew your working with when you clock on, what their expectations are. If you're shy and don't really get into it, then again, being a crew trainer isn't for you :)
