ya ive always gotten challenged just cuz they know i know MA. Usually my friends come at me with or a barrage of punches (all of which are slow and way off target lol) and i just a simple hold or takedown and they are amazed. It's just curiosity not ignorance cuz not a whole lot of people can do it good. It would be like if u met someone who could fly... of course you'd ask em to prove it just out of curiosity.
