Taxi Driver Online

I hear the same round here. Talking to the local hack a while ago he was moaning about the amount of tax he had to pay. I asked him how many miles a year he drove, his mpg and his hp. A few days later I told him how much he took a year within £2k. He was puzzled how I worked it out.

I told him if he worked less, he'd earn a bit less, but that would take him below the tax allowance, so he'd be actually better off. why work to make a loss and pay the taxman? Raving mad pal!
