According to the matchmaker, the object can be voluntary or charged, which is purely voluntary.

Some blind date is to mobilize relatives and friends around to help blind date, so this may be a personal exchange, and there may be no charge, but some material thanks should also be properly expressed.

There are also some organizations or individuals who take blind date as their profession, which are clearly priced, which is equivalent to providing you with a service, so the appropriate fees are also reasonable. Of course, if you can't accept the charge, you don't need what they offer. You are free to choose. I wish you an early beauty.
