I WAS THINKING THE SAME THING BUT I JUST DO IT AND I MOVE ON. BUT THATS A GOOD QUESTION

To justify their jobs?

[pattersondebra]

I always wondered the same thing. Not only to they repeat the questions, but they let you work on them for 15 minutes and then say you dont qualify. I sometimes can work on survets for half a day and only qualify for one or two.
