In my own opinion you are to act respectfully towards the artists, employees and the general public. however criticism is allowed artists love a little friendly banter about a piece (note: you are not to ever interact with a piece unless told to even then you are to be careful not to break an expensive piece of art unless you plan on paying for it and apologizing profusely)
