Times has change and change alot! In Mid 80' when I started TKD my dojan was nothing but a little one with front desk, a wood floor and a locker room with one shower smeling like hell!! Even that my ambunim has many students of all ages, from kids to seniors, all classe was crowded and people come in and enrole almost every week, and this was cause my sambunim was one of the best of my state, he was one of the first tkd practicioners of the 60's in my country. Ramon Alvite was a top notch sambunim and everyone wanted to train under him, simple he was the best, in his Dojan you must sweat blood (literally) in every training sesion and in every promotion examn, one's have to be well pepared to eamination if not, simple, you won't pass the examination.
These days the dojan must be lika a McDojan to have bussiness sucess, it has to have a large training area,alot of mirrows,be super clean, smell like strawberry, have a shynning locker room, a small store where you can buy the chest protector and all, tshirts,training pants,mitts and even some wooden weapons ohhh I almost forget having a small coffeshop AND some Tae Bo, Aerobics or Pilates classes for moms.
Having a McDojan to be sucessfull in bussiness is good however the sambunim never has to forget the MA inside TKD and never forget the practical ense of TKD inside SD. If a MacDojo has all the bells and whistles and have the Martiality in his core, blessed be.
