My cousins/friends and I were walking around Planet Hollywood when a guy asked us if we wanted to earn $10. We were uninterested at first, but we had time to kill before our check-in.
The guy told us we had to preview a new show (Skunk Whisperer) and fill out a survey. This all took about 20-30 minutes. Afterwards, we went up to the window, told the guy our names, and were handed a check for $10. Legit!
The next day, my cousins and I were approached again to review something for $5, but this time, it was to test out different coffee creamers. We had time to kill before getting ready to go out AND I happened to be craving coffee, so yet again we got sucked in. 20 minutes of my time to earn $5 sounds a bit pathetic but hey! We're in Vegas and usually I lose much more than that on a slot machine! Also, I got free coffee =P
