I like them both, but I like the second one better.
To me, personally, a market researcher is more likely to be knocking at the door (gates, whatever) and hassling the occupants, rather than preying on people just arriving. So the second one makes more sense to me.
But both are good. I don't know why you would have rejected the first one. But then, I'm not a professional cartoonist, so what do I know?
