"I would like to bring up an encounter with one of your flight crew that happened to me on a flight from Narita to Singapore on xxxx December 2010.
"I was on board flight xxxx departing Narita for Singapore and was seated in economy class seat xx. This being a AAA flight, my seat was in the cabin directly behind the Business class section with a galley between the two cabins.
"After take-off, the crew started to serve drinks to the passengers. I suddenly developed a stomach ache and had to use the toilets. I stood up and saw that the toilets behind me were being used and there were other passengers waiting in line for them. I was also blocked by the drinks cart which was between me and the toilets.
"At this point of time, I had no choice but to try and use the Business class toilet. I went forward and saw one of the toilets was empty, and went to use it.
"Before entering the toilet, I saw two crew members near the toilet who did not stop me going in. After I had finished, I exited the toilet and started walking back to my seat.
" I heard a sound behind me, and when I turned around, I saw a senior crew member whom I recognised to be the In-flight Manager behind me and he in not too many words began to "scold" me by saying"These toilets are not for your use, they are solely for our priority passengers, you must use the toilets at the back. Do not use these toilets again".
"I was too stunned for any words, and I stood there and just replied OK. I then turned around and made my way back to my seat. I guess this guy was still not finished with me as he followed me back to my seat and continued to stare at me.
"I would like to admit that I may have made a mistake by using the Business class toilets and I will not make any excuse for using it except that it was an emergency to me.
"What I really expected was for your crew to speak in a better manner and tell me instead of treating me like some child. I may be in economy class but when on business I do travel on business class on certain sectors.
"I cannot give you the name of the crew, as I was too stunned to take down his name, but he was definitely a senior crew because all he did was walk around the cabin not doing anything.
"He had a crew cut and had quite a lot of grey hair. I also want to inform you that whilst he was telling me off, there was also another cabin crew member near him, and I could see from his face that he was quite uncomfortable to see and hear his senior treating a passenger in this manner.
"I am writing this not so much to get things from xxx, but to highlight the 'new' kind of service cabin crew are giving to passengers. I am sure that dealing with the millions of passengers XX handles this has to be part and parcel of the job, but I as a Singaporean who always flies XX am very shocked by this.
"Kindly assist me by investigating this matter, as I know a simple letter of apology will normally be the case that Companies send and also to say that the person concerned will be counselled. In this day and age all airlines etc are doing the same for customers, but the difference has to be in the customer service both on the ground and in the air. I know this as I have been in the service industry for the last 30 odd years and have just retired.
"I would like to be able to receive a personal apology face to face from the crew concerned, or I may have to take this matter further. Please understand that this is not a threat."
