Ya knoooow... I used to go to the Beaverbrook Art Galley in Fredericton, New Brunswick often and I would avert my eyes from a Dali in the main entrance atrium, view the other works and then spend long periods marvelling at it as a grand finalé to my visit.

The staff were a bit upset at me once as I brought in a folding chair and sat for long periods in front of some works. I explained I had arthritic knees and I was not interferring with other patrons, that they had wheel chairs available... they adopted a policy of allowing "chairs", "until further notice." Haven't been there for years as I now live elsewhere.
