Some people are just born to be difficult. Social media strikes again as this is an "all about me" story. The FA in question knew what the uniform choices were when (insert proper pronoun here) decided to accept the job. If (insert proper pronoun here) wasn't satisfied with the choices, or felt personally violated by them, why did (insert proper pronoun here) accept the job? Sorry, I just don't have any mercy for someone who accepts a job knowing they will have to wear a certain uniform, and then complains about choices that are available.
What's the point of an open door policy if inside the open door sits a closed mind?
