Worst manager ever.

Good day I am a really unhappy with the manager at the shop called Maria, I was a paying customer and noticed the disrespect and how she treats her employees, clearly states we are putting people on chairs and positions they don't deserve, I'm not sure what one of the employees did bt I believe we all make mistakes bt you do not tell an employee in front of customers and other employees too #fix their life#spoke to other employees and their comments towards their manager is really said, I believe mental health is very important let employees enjoy coming to work each and everday. HR NEEDS TO INTERVENE.
