The toilet outside the 380 flight deck is a disgrace and should never be allowed it's only a matter of time before there is going to be a serious incident with a pax gaining access to the cockpit. The regulators should not allow it but somehow Emirates get away with it.
Regarding having 2 crew in the cockpit it's a knee jerk reaction which potentially could be more problematic. Regarding fitness to fly and mental issues I really have a problem with professional pilots being unable to operate a sector without having to pray for 10 minutes...again never going to be addressed by the company for obvious reasons.
