I have to agree with Molly T., but I also need to add that the rooms you go into are so small, hot and stuffy it's uncomfortable. Also, the guy who does the survey only asks a few of the questions, and puts in the answer he wants to on most of them. I find this practice quite unethical. This has happened to me during the three separate visits to this place, I was very surprised that they were that unethical right in front of me and my husband.
I did this twice by myself during the last few years and then once with my husband, and all three times were very similar. I feel this place is not only ripping off people who take the time to take their surveys by initially offering more than the $2.00 they actually pay, but they are also doing their clients a huge disservice by lying on the interviews.
