That's the funny thing. Singapore obviously is very into rules, following rules, etc. And in a sense their airline should reflect their (tiny) country.
But yet service is really good on SQ (in economy it surpasses almost all other airlines, in the premium classes other carriers step up their game).

I've been through Singapore a few times, but it isn't like they in general have great service. So, that definitely doesn't reflect their culture.

And Singapore is also supposed to be an IT hub for southeast Asia, but SQ's IT is horrendous, as everybody knows.
