Bell staff not welcome, do not laugh with customers, distinguish Vietnam and foreigners, need to be trained again. On the contrary, I am very satisfied with the staff on the club floor. Buffet staff is worse, guests do not know how to say hello, do not know thanks, and expressed uncomfortable with the customer. This is the fourth time I have stayed at a hotel and are considering whether to return for the next stay or not. I need something from the management side at least from DOR up through my email.
