Many instructors tend to bo-chap the trial lesson guy, I was a
trial lesson guy once too, I don't know why. Maybe too many people
go for free trial lessons and don't come back, so they sianz and
rather spend time teaching paying students.
Why not try paying for one month fees, then go train, perhaps
you'll get a totally different perspective. You don't lose anything
because you're training, and you really learn about how the lessons
and the instructor is like. If you don't like it, next month go and
try another martial art or a different instructor.
