And the Regional Ad Buyer and the Digital Agency will convince themselves that attributing every single sale to that advertising spend is valid and acceptable accounting practice, when most of the client's product practically sells itself. And they'll do this for a decade or more, until Global Head Office notice, then they'll pull the plug with 3 or 4 months outstanding unpaid, leading to ~100 people getting laid off with zero notice and tens of thousands of dollars of unpaid monthly salary and entitlements.
