I believe it is more reasonable not to allow somebody to fly it then
 face all the possible tragic consequences of an accident. Therefore
 saying "no" at the last moment was not a matter of trying to
 humiliate Mr. Sharma by any means as he claims - but protecting both,
 the person and the glider. It's also worth mentioning that our
 decision was confirmed by the local gliding instructor who shared our
 doubts. Mr Sharma said to me personally that he had only 200 hours and
 no experience on racing class gliders.

You did not address Mr. Sharma's assertion that the Diana was being
de-rigged during his checkride.
You had his aeronautical experience before he arrived at the field.
If you were not going to let him fly, you should have told him as soon as it
was determined.
I am a USA Flight Instructor and a ASW27B owner. I have seen people with
inflated ideas of their ability and can usually determine this quickly
during a check ride. With the right training in the ASK21, the transition to
a '27 is easy.
In any event--if Mr Sharma failed his check ride, he should have been
infomed of that, and exactly what he did wrong. That could be lifesaving for
Mr. Sharma.
Either way, it is a pretty shabby way to treat a potential customer.
