If they have a full room to themselves, a DC might let them fuck around without supervision. There's no way I would let them into the structural/electrical bits without seeing his signature under the mother of all responsibility waivers, though.

After that, if this was just a regular asshole I'd hope their fuckaround trip goes without a major incident both to save myself from a lot of trouble and out of common decency towards a fellow human. This particular asshole would really be testing the limits of the latter.
