The room itself of MO BKK remains of my ultimate satisfactory standard, from sound proof, room amenities, air-conditioning system to bath room comfort...etc. I especially like the ventilators inside the cabinets. So far I haven't seen other similar facilities like that. Service-wise, the service level staff still keep their certain professional standard. However, the security team has been of some notable concern and further on the senior management too, yes, senior management. As my friends took another flight to arrive a few hours later than me, I went out to check the street condition if there was some flooding around the MO area. So naturally I put on my sandals. At that time, I got a sms from my friend that it was another 10 minutes they would be reaching the hotel. So under such circumstances, I decided to stay around the area outside the hotel entrance since I was aware that waiting in the hotel lobby with my sandals on isn't appropriate. Then when it was time I thought my friends should have arrived, I went back to the lobby to welcome my friends for their first time coming to MO. However, the security person rudely questioned what I was doing there and even claimed that putting on sandals is not allowed in the hotel. I immediately told him the reason why I was outside the hotel lobby area as I was well aware of that. Unfortunately that security person didn't have any apologetic manner. I promptly went to the front office for bringing up a complaint. In the meantime, my friends arrived and so I had to make it brief. Anyway, when I returned to the room, the house manager called for a serious apology. So I took it and further explained the inappropriate manner of the security team. Then as I recall last year, another friend of mine was warned at the entrance from the riverside and questioned if he was staying there. I then wrote to the senior management that why this group of people being Asians having such a miserable discrimination to Asians, especially when I noted a no. of caucasians wearing sandals in the hotel lobby or restaurants...etc. The disappointment is that the senior management replied only after we left the hotel - took 3 days. So I didn't reply to their "form A" reply. Having said that, I still enjoy staying at MO as far as I won't bother to care about their senior management.
