Hungry Jack's Australia

Dear Sir/Madam.
I am a long time customer of Hungry Jacks In Beresfield. In the last few months I have noticed that a new and very recently recruited manager named 'Jessie' has been cruel to her staff members when she is rostered on. This Jessie spends her time yelling at the staff members who always seem to be so hectic + understaffed as it is. I notice her behavior when I am waiting for my food order and I am appalled. She often ignores her staff members when they are calling out for help to make drinks or the likes, she demands respect from them but fails dismally in giving/showing any herself. I have seen her yelling at the staff members in full view of customers when the store is busy. I have seen staff wanting to leave as their shift is finished and she will not 'sign them out', but rather leaves then hanging around like a fool while she is busily crying her eyes out in the corner obviously not coping very well with the stress. Whenever I go in, she is always in tears at some point, so why is this person a 'manager' when she is so poor at her job.
I do not like going into this store now as I hate the way she treats the young staff and her rude attitude towards them also. I have also noticed that the turn over of staff is quite high as the same familiar faces do not stay very long at all.
I am so hoping that this idiot manager gets a swift talking to and reprimanded for her cruel actions + behavior.
Most Sincerely, Mandy Spacek.
