As a humble PAX I do think it astonishingly rude that someone would make a remark like that-as many hear have said what on earth did she know since you cannot see much of whats going on from the passenger seat. Its a bit late now you have posted it here to say forget it-similar things happen to everyone early in careers but usually when people are addressing someone with a job thats a bit easier to understand than a pilots. Like profesional footballer who screws up and has 30,000 people, all of whom are better than him in their minds- yelling abuse at him.
Mind you I always felt for the pilot-not sure which one- of an SAS MD81 which in contrast to generally very smooth arrivals hit the ARN tarmac with an almighty crash bouncing many overhead bins open only to hear the in charge CC announce in English."Ladies and Gentlemen AS YOU MAY HAVE NOTICED we have arrived in Stockholm" ,talk about damning with feint praise.
