Yeah. It's why me and my brother got 'em as soon as we found out about them. Learnt the hard way that they can be ripped off.
I never say no to more combat instructors. Hell, I have no issue with you starting that now. If there's a class already offered you want to help with, just have a chat with the instructors, and organise it amongst yourselves.
If it's a new one, just tell me the details, and I'll add it to my timetable.
