I certainly don't quit a job over this. I'd tell a manager that you are aware of the policies and that you do break boxes down. Manager was rather abrasive and spoke rudely but quitting over this is rather extreme.

Over the course of my professional career and list of side jobs I had to keep to supplement my income, I encountered tons of people quitting their jobs over every little thing. I could never afford to simply quit a job and just cannot relate. For a teenager that incident could be a lesson that there will always be nasty bosses and annoying colleagues and stupid rules etc

The trick is to stay true to your own values and standards and don't stoop to their level. In cases of harassment and bullying at work there are always higher level managers and HR one can complain to.
