Market Research

I have several encounters with market research agents wanting to get my opinion to participate in some sort of survey. A telemarketer from a market research company called me in my private hours to get my opinion about certain subject. However, I don’t have time for this and this people will not stop until they get you on the phone. Mind you they took 20 minutes of my precious time to go through with all the questions they asked. Another market research strategy is by email. A research company will pay you some money just to fill-in the survey questionnaires that they sent on the web. If this happens to you during dinner or during sleeping time, what would you do?
