Is who would pay for the date really a big factor in anyone’s decision about who to date? Seems like a pretty basis on which to start a relationship!
If you're looking to settle down then the payment factor probably doesn't matter so much, in which case you could place TWIBS at your local pizza place, bowling alley, hiking trails.
The idea is to help people find what they're actually looking for instead of assuming everyone is out to find "the one"
