The tone of discussion in this thread needs to be taken down a couple of notches.
I haven’t read anyone trying to excuse the lack of water on the flight. Clearly, if it needs stating directly, this was v poor and unacceptable.
What we don’t have (if I recall the full thread correctly) is a concrete reason for the lack of water. We would need to know this before speculating if there is any read-across to other checks, procedures etc.
