Being a so-called 5 star hotel, especially one that's under Hilton Hotel franchise, the serving staff in the restaurant (the one that serves buffet breakfast) definitely needs more intensive training, if they are trainable. While my wife and I were having breakfast, sitting right next to our table were 4 hotel staff, chatting loudly, probably enjoying their free breakfast. One was in fact occupying one of our empty seat in our table, showing a complete neglect of boundary and personal space. At the end of their meal, the one who was intruding into our space, even tried to light up his cigarette to smoke, in a "No Smoke" restaurant. If my wife did not reprimand him, he would have just go ahead and do what he pleases. Of-course, not a word of apology was offered for his offensive act. Apparently he thought that was within his right to do so, despite it was a No Smoking facility. Such a kind of behavior was shockingly appalling and would not be seen in any decent hotel anywhere else in Asia, definitely not in Hong Kong.
The serving staff in the restaurant was inattentive to the guests' need. We ran out of paper napkins for our table, and none of the servers paid any attention, even though several of them walked by our table many times. Neither did they come to pick up our empty plates after we finished. Perhaps that's their definition of "buffet' dining, because in Chinese it means "self-help" and they are taking it to mean literally, that the guests were to help themselves??
