And it doesn't even need to be government regulation.

The hospitality industry has self-imposed standards as to what kind of amenities a facility should have in order to rate as a two-star hotel, three-star hotel, etc. Things like TV, shampoo, and hair dryer are on that list. If customers make enough noise about bathroom doors, the rating organizations might actually add that as a requirement.

Yep! Government regulation is basically when the industry puts their heads way too far into the sand.
