When I worked for what was the fastest growing public publisher in London over thirty years ago, salespeople actually shared their tax slips to boast. "Super tax" was the euphemisms for how much was calculated you needed to have deducted from your payroll every time you hit a campaign out the park and increased your tax offices estimate of your annual return. Which we did. Often. See the Guinness records book for the PGA tour guide of'93 which was the apotheosis and the end of that lark. (Almost all advertising it weighed six pounds or something crazy but quite sane compared with the first dollar points paid to direct sales)
