In traveling Y, C , or F, I have never encountered any one FA that is disrespectful towards its passengers when traveling with SQ. Some can be a bit less than what I'd expect, but never anything of the kind.

I do not understand the need for swearing anyways when civilized actions can be done on the part of the OP. No matter how bad the FA treated you, it is by no means how you should treat FAs even when you are sleep deprived.
