Ok, I might by slightly biased but I 'third' speed dating.
I met my wife at Calgary Speed Dating back in 2006. This was one my first forays back into the dating world after my divorce and it was a lot of fun.
Oddly enough we bought the company about 2.5 years later and owned it until 2013. Yes, i know cue Remington shaver jokes - "I liked the shaver so much, I bought the company..."
We had many dating and marriage successes amongst our clients. The vast majority of people had a great time at our events.
