It didn't bother me, because the point I took away from it is "Sometimes it really pays off to pay more attention to the changes around you." (busker where there isn't usually one, f'example.) When I'm working with a "Notice the beauty around" mindset, I'll notice stuff like that. I like my life when I do that.

I thought it was a totally fascinating experiment, but I'm not dismayed by the results (and, as you say, $32 for 45 minutes is not bad.)
