Just had a knock at my door. "Hello, I'm with a market research company, I'm in the area I'd like to take 5 minutes of your time to ask you some questions, please", says she. "Certainly", I say, "How much are you paying?". She looked at me for a moment, then said "Sorry?". So I told her "Look, your company makes a profit by collecting and collating data, that data has an intrinsic value. It would be remiss of me to simply give it away for free. How much are you paying for my information?" "I'm sorry, I can't pay you", she said with a look of resignation/annoyance crossing her face. "Goodnight then", I said and closed the door on her. Petty, I know. But hey, she shouldn't come round door stepping on a Saturday evening.
