20 minutes for 12 bucks? That's a bargain.
I think there's a whole new business here. Maybe you're lonely for your ex-wife. Maybe you just want to remind yourself why you're single. Maybe you're getting dangerously close to dropping by her place late some night to see if one spark remains.
The answer is professional henpecking. You go see a really bitter professional ex. Fifteen minutes, half an hour... maybe some high-performance guys could take a whole hour of rabid browbeating. Of course I think good hissy fits should command higher wages than $12. But you could work that out at the (cough) Fair Tirade Commission.
