Very interesting topic. My reasoning would be
1. the person is average height, but well over 350lbs.
As long as I get his Doctor's bill of health then everything is ok I'd slowly work him to get himself fitter and let him control how hard to push him.
2. the person has multiple face peircings and tells you they won't remove them but is willing to risk it.
Its My Dojo - thats the rules, like them or 'Goodbye you are the weakest link' go find a MCdojo who's only interested in get money from you
3. the person mentions, for religious reasons, they will not engage in any 'ceremonial' or iconic things like wearing rank, bowing, or speaking a foreign language nor recite any codes.
Again, Its My Dojo - thats the rules, like them or 'Goodbye you are the weakest link' go find a MCdojo who's only interested in get money from you
4. the person is obviously a transgender female, (was male-is now a female, without operation).
Hey in a Gi, we all 'look' the same so as long as they personally don't make an issue of it they'll be treated the same as any other student
5. tells you they will pay x money to learn 1 particular kata or skill.
Hey, this is where I see $ signs in my eyes (Welcome to Mcdojoland) I would add that they must purchase a Licence (Insurance) and GI and yeah no probs $'s for a Kata they could learn it from a book/DVD for $20
6. the person happens to be your sibling's ex-spouse who is cuurently going thru a nasty legal battle with each other.
Sorry, Family is first, I'd recommend another Dojo for them to train in
7. a student who always pays on time and in full, but consitantly only shows up to one class per month.
As with other replies, I would have to speak to them regards what they want out of the style. if it transpires they have other issues, try and resolve them they might start coming more often
8. a person who has double the amount of MA experience as you and visibly more skill than yourself, but is humble about it.
The style I teach is not traditional Karate so there are no Kata which they would know, I find that those with Experience make the best students. I never look at my students as lesser mortals, I see them all as future Instructors
9. someone who is not particularly interested in the Art, but more in the exercise aspect.
tell them to find a Mcdojo or join a Gym or even find a 'Taibo' or 'Boxersize' with the Lycra brigade Karate is about the whole not just exercise
10. a student of another school, who you know will be taking the other art simultaneously.
Again, The style I teach is not traditional Karate so there are no Kata which they would know, I find that those with Experience make the best students. As long as their other Sensei is happy for them to 'Cross tain' so am I but as long as it doesn't interfer with their learning - I was studying Ashihara karate, Krav Maga, Atemi Jujitsu and Wado Ryu, I've wittled it down to Ashihara Karate (that I teach) and Wado Ryu which I study as white belt.
