I think you missed the point. She's not working behind the desk of an easyjet flight that just got cancelled. She's responding to text on a screen. I've had far worse jobs than that.She got three hours sleep because she is trying to sort it out. And she is fairly regularly replying to at least the tweets she can.
I don't think your comment is fair at all.
She is just a human being and is trying to take some kind of personal responsibility for what is clearly a problem with wider systems in the company.
And really, all we are missing is a fancy toy. This isn't a life saving device that people NEEDED this week either. Its a few days late. Its not like they are going to take our money and run.
If she feels she could only have 3 hours sleep because her job depended on it, then that is wrong. Is that the case? Why you even know about her sleep patterns - is she telling people on Twitter?
