itto say that I have seldom seen anyone leave a tip for a complementary breakfast at any hotel to date. Maybe those that are thoroughly indoctrinated at AU do.
Depends on the hotel. Not much reason to leave a tip for microwave omelets at the Hampton or stale cinnamon roles at the Holiday Express. On the other hand I've had some pretty amazing breakfasts included with my hotels in Asia. At the risk of bragging the JW Khao Lak came with an included breakfast that was among the best I've had and easily worth another tip each and every day of my stay.
