Before I was married 39 years ago.
Speed dating. Show up at a bar/club around 11 pm when everybody is pissed up, the girls are tired of the drunks, pick one up. That's speed. Didn't even need to buy a drink. So free.
Its too bad the old school style of speed dating doesn't seem to exist anymore.
Why not put something together for your area, and start a speed dating club. Do some advertising, organize them for say every 2nd Saturday. Personally I would prefer them to be outdoors, maybe in a park. Each pair walks a lap around the park and talks, lets say that takes about 10 or so minutes, then switch. In 90 minutes 9 pairs meet, in 2 hours 12 couples, you get the idea. It is calm, relaxing, and not sitting across a table like a cheesy job interview. There is no pressure, just people getting out for some non-strenous exercise, fresh air, and hopefully sunshine. About 13:00 or 14:00 hours on Saturdays. Ask people to please donate $5 to help with advertising, and a simple website cost. You can build your own cheap and easy on Go Daddy or similar places.
