As a matter of interest did they turn up with that "book" of a checklist for the PA28? I takes 15 mins to just get up to the point that your ready for departure.
I have a small collection of those from my modular school as well.
It tells me to turn the Pitot heat on three times before I take off in perfect VMC!
The worst I ever saw however was an otherwise thoroughly well adjusted place that I rented a C172 from in Canada whose checklist was twice the length of the one here at my CPL school. Even the instructor checking me out at-least had the good grace to act embarrassed about it and we both knew it was going in the back the moment the instructor got out.
