I am a tax guy and there is a famous case about the IRS auditing a house of ill repute in New Orleans. Since it is a cash business, there were not any sales. The IRS agent then asked the cleaners how many sheets and towels that they cleaned, and then the IRS imputed all this income. I have calculated the sales contracts and my numbers were very high and in reality, the sales numbers or cash receipts are very low. The only way to gauge sales is the amount of production in KL, bottom line.
