I guess your name is Asinus.
The Metropolitan Transportation Authority is the parent organization of several entities, which includes the Long Island Rail Road Company. The sheer audacity of claiming that a parent organization needs a child entity's permission to allow a third party any degree of access -- especially when considering an effectively reversed agreement that is still active to this day -- is so far beyond stupid that it's virtually impossible to consider the person making it highly misinformed, particularly around these parts.
If you're looking for a toilet, look elsewhere.
