Do all Hilton properties (which have a restaurant) offer free continental breakfast to HH Gold members?

From HH:
Gold VIP On-Property Benefits
A space-available room upgrade, including breakfast.**
You will be upgraded to an Executive Floor room (where/when available) at time of check-in. If an Executive Floor room is unavailable, you will be upgraded to the next best available room from the room type booked...
...In addition, you will receive complimentary Continental breakfast for you and up to one additional registered hotel guest each day of your stay.

...If an Executive Floor room upgrade is unavailable, you'll still receive daily complimentary Continental breakfast in lieu of lounge access.

Just wondering if all Hilton Hotels are required to do this, or can some owners refuse?
