Yes, I had a punt a few months ago with a girl who said that some regulars pay for 4 hours (at the going rate), thats around £600, to take her out for lunch and then go back to her place for a screw.
I though, WTF is all that about, then I met up with an old mate who'd just bought a Lamborghini for £160,000 whilst I'm driving around in my Vauxhall Astra. Kinda puts it in perspective.
