I daresay I shouldn't say why at this stage but I'm investigating rules and regulations about making somewhere into a festival venue. So I faithfully downloaded the Fringe 'Guide to running a venue' and have been scanning through it.

My favourite portion to date concerns health and safety info and the use of scaffolding to support audience seating. It says, quite reasonably:

The safety of the audience is paramount. It is both your responsibility and in the interest of your ticket selling to stop and think: would you pay money to sit on this structure without life insurance?
