There are no standard in dealing with pop-up problem, my business guest faced with rudeness reaction about early check-in. The thing is I came and talked with one reception about early check-in one day before my guest arrival and we concluded to upgrade room in order to make sure that there will be available room in the next morning for my guest to do early check-in. Everything turned upside down, my guest arrived, they said only no no and no can not "you have to pay one night more and we didnt know anything about this", so I called in and talked to one reception and she barely listen to, it took me about 15 mins to made her understand, which was such an unpleasant conversation. Then I asked her to tell my guest once room is ready, no one told him until I made a call again 30 mins after the time we deal on the phone, and the answer was "the room is ready", but no one invite my guest to come up!. Before this my guest was waiting in the dining room, and waitress didnt allow him to order a cup of coffee because he has no room yet and didnt say that good. For more information, this was the first trip to Bangkok for this guest, and he came for open up deal with us. This is such a ashamed on us for this things, we won't take a risk for my guest anymore in this hotel.
