Seriously I have no idea why people need to goto a dating agency to find a partner.
If you are still young, everywhere are opportunities. Eg even when I signed up class 3 and class 2b course, there are tonnes of opportunities to get to know new people.
Whether we can get what we want is = you goto a dating agency to try your luck
And if you are old, just walkin to a bride shop and buy one.
A dating agency doesn't offer any advantage at all, with that exorbitant charges.
A secret tunnel dating service is totally a different concept and cost effectiveness. You pay something like $10 per try, barely enough for a meal.
