Well, without wanting to sound too serious cos I did ask to a degree with tongue in cheek......
...it is generally "known" that an unusually high proportion of male flight attendants are gay - of course looking gay does not mean one is gay (and vice versa) - and although this is a generalisation, I know a few BA
cabin crew who confirm this to be the case. So no, I don't directly ask when I request for a Coke (tho my friends do get asked/offers - esp from First passengers).
Nevertheless, I am not asking about the accuracy of this well know generalisation, I am asking why it is likely to be the case.
