Burger King complaint: Employee issue

The assistant manager at the Tullahoma location in Tennessee has done many things that should be addressed. His name is Dylan and multiple occasions he will be drinking on job. He puts beer cans in the large cups and drinks them all shift while he sits in the office and plays on his phone. Which he constantly sits in the office playing on his phone rather than making sure the store is in order. Lastly he will be on the clock and leave the store and come back and clock out when his actual scheduled shift is over so he meets the required hours for the assistant manager. And to top it off he has threatened employees and over the 4th July holiday he got in a fight with 2 employees which caused those employees to quit. And of course alcohol was involved. I honestly don’t expect anything to be done because the manager knows and does nothing which he is supposedly leaving to goto another store. Which means Dylan will be taking over the store and if what he does now continues it will be a disaster.
