How is he going to know they're liberals? If I was a liberal I'd just claim to be "conservative" so I'd save an extra buck. It's like that Chicago bar that was offering 1 free drink to anyone who voted for Obama in 2012. If it wasn't so far away, I'd show up with 40 of my conservative buddies and we'd all claim to be "Obama voters" to stiff those guys.
During my last few years before retirement, I charged liberals double, then triple, then quadruple what I charged decent people. They paid happily, but I finally decided it was not enough. I’m not willing to work for a liberal at any price - and that now includes work that generates tax revenue for the communist in our White House. Who is John Galt?
I like that. A “liberal tax.” Tough to do, though, since many lefties are liars.
I worked with a lib woman who bragged how they cheated on their taxes.
How much would Romney or Christie pay?
How does he ID the libs? Watching them get out of a Prius in the parking lot? Gray haired guys with pony tails? A copy of New York magazine under their arm?
