Pre-dating...should I go?

A friend just asked if I would accompany eher to an event called Pre-Dating.
I'm really not too eager to spend $35 to meet....er... pre-date someone (not to mention too underpaid).
I have not been to one of these events, but am pretty sure I understand the concept. (Concept= musical chairs involving bachelors or bachelorettes).

Some testimonials form their website:

My first experience with 6 minute dating was with you on Wednesday the 11th. I
found it very enjoyable as it's nice to have a captive, unmarried, female
audience.

Captive? As in held captive? For some reason I find it odd and funny that he chose to use the word captive to describe his audience.

This is so much better than Internet or Video dating for the not-so photogenic
(such as myself!)

Oy. Not to be shallow, but it does make me wonder about the quality control.....

The little bell rings and everybody has to move on, nobody gets monopolized for
the entire evening and I did not need to be forward or aggressive to get to talk
to the women I wanted to talk to.

This quote comes from the same winner as the previous one. I wonder...exactly how aggressive is he willing to get?

Informal survey- the majority of glowing reviews for pre-dating came from people age 35+. I'd be more enthused if I saw an euqal amount of testimonials from the under-35 set.
