I'll remember this next time I'm eating a doner kebab.  I thought it

The researcher gave a lot of very useful information to what was a
rather open ended question. They just needed a bit of nudging in the
right directon, but in the end I have learned a lot. I would give this
4.5 if I could but the initial generality of the answer stopped it
being a 5.
