I'd say he put a decent envelope in your phoca.. no doubt you saved him 7 figures. To be fair, mytaxi/Hail0 owe you for that too. How much would they have spent putting vouchers in taxmen's pockets if they had to compete with Bill?
That's the second time you suggested I got food/payment from some firm or other. For the record, bar a cup of coffee from mytaxi last week, I didn't.
