I bet there are other smartasses in high position in France who also give "advice" or are asking questions and they may be more difficult to ignore. Some managers have the courage to tell these people to f... off but a lot of them don't have the spine to do so so it still may be a problem for the firefighters.

I have gone through this process last summer in my company and it's really frustrating when people spend energy on questioning everything you do instead of helping.
