I'm not sure that crew praying in the first class cabin would go down too well with most pax, particularly outside of Muslim majority countries. The pax are paying us substantial money to perform a specific task. How about a Buddhist waiter meditating next to the table he is serving at the Savoy? at the end of the day, we are being paid to perform the role and project the image required by the employer, flight and cabin crew alike. It is not religious intolerance, it is business.
