Hospitals are full of 'life and death' situation. If everyone were to behave like that, things would stop working or be severely slowed because you can't work correctly when you got that guy breathing on your neck constantly. You lose time answering to load of demands from people getting angrier and angrier because they feel that they don't get the care they need. That makes you angry. Other people are getting less attention, they get angrier.. Etc etc.

I believe you have the right to say it when things are not right, but there is a fine line between that and the behavior he described.

And he wrote that he went to an expensive hospital, this isn't some low tier hospital filled with under qualified, under staffed personals.
