It's not just looks. Service ATTITUDE is far more important. SPG normally has farked up service attitude, but see $$$ and the attitude suddenly appears.
Those who went to Taiwan for training during NS should know. Flew chartered SQ to Kaohsiung and back by China Air. The difference in service standards is like heaven and hell, though both airlines' stewardesses can see that we are conscripts. Taiwanese stewardesses are so nice, fat also I don't mind, but they are mostly slim and prettier on the outside as well as on the inside. After this, I knew exactly what to do. Never again did I fly SQ unless forced to e.g. company policy, all other flights booked, etc.
When you already have the 5Cs, you can, no should, pick and choose carefully and avoid like the plague those that make a big deal about the 5Cs. Sinkie girls, with or without kebaya, should be avoided, unless it's a one-night stand. The Creator has made many females of all shapes and colours. No need to limit yourself to the Sinkie variety. :p
