Fast Food Pays The Bills?

I recently noticed on my receipt from Taco Bell that they have a survey on the back and it states that one customer every week wins $1,000 bucks or something of that nature. I've noticed these before from other places too. You know, Target, the grocery store, etc... It didn't hit me until yesterday, but do people really ever win money from these things? Does anybody even participate in the surveys? Or does everybody slough it off like I do, thinking it's silly and impossible, and so the money just sits there? Is there really any money at all to be won? Maybe there isn't and it's just a way to get your opinions. I mean, have you ever actually heard of somebody who won money from a survey for a store or fast food place or from the yearly Monopoly game from McDonald's? Anybody? Is it legal for them to not award somebody? What about Wheel Of Fortune? Everybody got a Wheel Watcher number? Cause I know I do! Maybe if I sat at home and did surveys all day I would actually become rich. I want a full report from the professionals on this. Whoever they are. Who knows!
