I agree,

Invariably I think because the simpler applications are simply views of simple database queries then the client base assume you can just *throw html* around your data and everything magically works.

As it happens my current internal client wanted to know why my project would take 30 days instead of 10 for this very reason. Thankfully when I broke the time down they accepted it. Sadly I still only got 15 days to do it (I've just started day 11).
