This is a case study on how to ensure you will not get a representative response.  Obviously they only want to hear good things but this is pretty egregious.   The huge "Want a Free Sandwich?".  Having the words "highly satisfied" in a different color.  Repeating "free sandwich". And, my person favorite, having "if you're not satisfied" in much smaller text and telling you to call and not to put that in the survey.  Ladies and Gentlemen, I present you statistics.
