Stand up and believe that the way you are conducting your survey is for your customers, not just you alone. Don't try and fool people, were not fooled.If you are going to have a couple fill out a survey, how about buy one meal get the second meal half off. After all, it appears this is a random selection. Not everyoneis doing this. Now, I am not looking for free handouts. As a matter of fact, I would have rather given the manager (and no disrespect to her) $5 to leave. It's obvious to me in this circumstance that this particular establishment does not want to give away anything. They want it to only benefit themselves.But if you are a business and you want true success in surveys, do it right.
