Genesis,
I can't comment on the lack of feedback or consideration from Qatar Airways towards others.
Perhaps instead of writing to the media, they should write to Qatar Airways.
However, I don’t think that a 5 star airline would ever stop serving alcohol or will ever favor a particular nationality over the others. If ever that happened Qatar Airways would be flying Qataris only (a very low number of passengers when compared to other nationalities).
As for the episode describe in this post, as Qatar Airways is a 5 star Airline,I expect feedback and a reasonable explanation for the security failure.
