hahahaha.........
this is a hoot.
for the battery survey, they have 5 different flashlights covered up on a table.
they put batteries in the flashlights.
then you pick up flashlight A and turn it on. shine it on the poster.
then they ask about 10 questions on that flashlight.
is the light bright, is it focussed, is the flashlight heavy, etc.
give that flashlight back to the worker and then pick up flashlight B
same procedure.
it took 10 minutes of my time, maybe 15 tops as i yakked about the day to him while doing the test.
they were testing efficient batteries in various flashlights.
the soda test similar in a way.
e-z bucks that day
i did have to show him an id , i used my hotel key to verify my name.
the survey was inside one of the buildings by the park across from the mummy and monsters cafe.
